1869 - Probably the biggest flood in Texas history -
Produced by heavy rain that extended into northwest Texas -
Tremendous flooding down the Colorado River from the headwaters
to the mouth
Account of flood by Frank Brown - Travis County Clerk, in the "Annals
of Travis County" -
"The highest and probably the most disastrous flood
that ever came down the Colorado River within a hundred
years occurred early in July 1869. Certainly none such ever
occurred within the memory of oldest inhabitants of the
white race. The floods of 1833, 1836, 1843, 1852, and 1870
did not approach it in volume within 8 or 10 ft.
Early in the first week of July rain commenced falling
and so continued at short intervals for several days. The
stream commenced gradually rising, but no apprehension was
felt of the heavy overflow. On the 6th, a tremendous flood
suddenly came down in solid walls, overflowing all the lowlands
and spreading over the valleys to the hills. The river rose
to the bluffs. The people thought the highest was reached,
but the water continued to rise rapidly, and much alarm
was felt. The river reached its highest mark on the evening
of July 7, at about 9 o'clock.
The rise was estimated at forty-six ft. The mass of waters
rushed down from the narrow and confined channel between
the mountains above, to the wider one below, with such fearful
velocity that the middle of the stream was higher than the
sides, and the aspect it presented was appalling."

heavy rain with 34-in. center in Hearne, 24-in. center in
Turnersville, just north of Gatesville.
Probably stalled long wave over west Texas and/or New Mexico
for period - Mid- and upper-level water vapor from eastern
Pacific - Low-level moisture from jet off Gulf into Texas
- and a series of short waves around the southern periphery
of the long wave.

heavy rain with 15.50 in. center at San Marcos, 13.80 in.
at Bertram, 13.60 in. at Somerville, 11.80 in. at Waco, 11.70
in. at Kaufman - Obviously a classic El Nino year - rainfall
totals 20 to 25 in. had fallen in the previous 3 months in
the area, and water stood in the fields between storms.
Very likely a long wave stalled over west Texas or New Mexico
Dec 1-5 and sent a series of storms around its southern periphery.
The Colorado and Brazos Rivers merged below IH-10 to the
Gulf because of the very widespread heavy rain, no flood-control
reservoirs on the Colorado or Brazos River, and debris dams
on the Colorado and Brazos Rivers.
The Colorado River dam was from river mile 28 above Bay City
to river mile 52 just below Wharton - The dam wasn't successfully
blasted out by the Corps of Engineers until between 1925 and
1929.
There were 180 drownings - Water was waist deep in downtown Bay
City - The Colorado River went over the right bank above Columbus
and made an island of the town.

1921 - Thrall Flood - A tropical storm formed in the
Bay of Campeche the morning of Sept 6, 1921 - made hurricane
intensity that afternoon - made landfall near Vera Cruz the
early morning of Sept 7 - veered right and fell below depression
intensity just as it crossed the Rio Grande at Rio Grande
City the night of the 7th - Light rain began falling in San
Antonio the 8th, which became a deluge the evening of the
9th, with totals to 18 in. in the northern part of San Antonio.
The 18 in. in northern Bexar County the evening of Sept 9,
1921, created a flood wave through downtown San Antonio 12
ft deep - The flow passed down Olmos and Apache Creeks into
the San Antonio River - People caught downtown tried to evacuate
vertically to upper floors - 51 didn't make it and drowned
as the flood wave peaked near 1:30 AM -
Water was 4 to 5 ft deep in the current St. Marys Church
and the Gunter Hotel. Olmos Dam was completed in 1928 as a
flood-retention dam to protect downtown San Antonio as a direct
result.
Thrall rainfall - 23.4 in. during 6 hrs/31.8 in. during 12
hrs/36.4 in. during 18 hrs/38.2 in. during 24 hrs at a U.S.
Weather Bureau station at Thrall is still the national official
24-hr rainfall record ending at 7 AM Sept 10, 1921 - The storm
total was 39.7 in. during 36 hrs - With 215 drownings statewide,
this was the deadliest flood in Texas history.
Eighty-seven people drowned in and near Taylor and 93 in
Williamson County. The confluence of the San Gabriel River
and Brushy Creek was 10 mi wide. Not an El Nino or a La Nina
year.

1932 - June 30 to July 2, 1932 - The State fish hatchery
near Mountain Home on Johnson Creek above Ingram recorded
19.6 in. during 6 hrs - 32.4 in. during 18 hrs - and a storm
total of 35.6 in. during 36 hrs in a widespread flood event
- Uvalde had 20 in.
Probably a synoptic scale upper low moved into and stalled
over the Texas Hill Country - fed by tremendous moisture inflow
at low levels from the Gulf - and at mid and upper levels
from the eastern Pacific - The winter of 1932-33 was an El
Nino event.
The fact that central and south Texas draws moisture both
from the Gulf at low levels and the eastern Pacific at upper
levels gives the area capacity for tremendous atmospheric
water vapor - Precipitable water quite often exceeds 2.00
in. and could be greater than 2.40 in.
Seven persons drowned in the Guadalupe River headwaters -
Disastrous destruction of recreation camps and homes along
the Guadalupe River - a daytime flood, which saved many lives.
In north Texas, Jim Ned Creek and Pecan Bayou dumped a peak
inflow of 235,000 cfs into Lake Brownwood - Lake Brownwood
saved the city of Brownwood.

of the International Bridge - In Laredo, the International
Bridge deck was flooded by 6 ft - nearly 200 city blocks in
Laredo flooded and about half the business district in Nuevo
Laredo was underwater.

tank at the Woodward Ranch, 10 mi north of D'Hanis, empty
before the flood by several reports, overflowed in less than
3 hrs - The tank was 21.84 in. deep - The Rowe Ranch river
gage 3 N of D'Hanis crested at 35.7 ft - The entire town of
D'Hanis was underwater, and 17 homes washed away - more than
a mile of Southern Pacific railway washed away, and there
were 5 drownings, again held down by the daytime event - Probably
an upper-level low that stalled over the D'Hanis area. Not
an El Nino or a La Nina year.

flow off eastern Pacific over central Texas - Widespread,
long lived, disastrous flooding over the Texas Hill Country.

1936 - A hurricane had made landfall between Corpus
Christi and Victoria June 27 and fell below depression intensity
that night as it moved into the Frio River drainage near Leakey
- A second tropical storm formed in the Bay of Campeche Sept
10, made landfall at Brownsville the morning of Sept 13, moved
across deep south Texas before falling below depression intensity
near Del Rio the afternoon of the 14th - This flooding rainfall
was widespread over central Texas around the right side of
the circulation. Not El Nino or La Nina year.
Worst hit was the city of San Angelo - From USGS Water-Supply
Paper 816, published in 1937 - Tate Dalrymple and others -
"Rains exceeding 30 in. in some places fell during
September over a large part of the Concho River drainage
basin. Three separate flood peaks occurred on the main Concho
River - Sept 15, 17, and 26, the flood of the 17th being
the highest.
The city of San Angelo suffered greater damage than any
other place in the State. On Sept 17, the discharge of the
South Concho River reached a maximum of 111,000 cfs and
caused stages which backed water up the North Concho River
to the center of the city. Just as this water began to recede,
the flood from the North Concho River with a peak discharge
of 184,000 cfs reached the city. The river channel was inadequate
for this enormous quantity of water and the river broke
over its banks, flooding large areas of the residential
and business sections of the city.
Below the mouth of the Llano River, the stages on the Colorado
River during the floods of 1936 were much lower than the stages
in the notable floods of 1935."
SAN ANGELO MORNING TIMES - SEPTEMBER 18 - "An insane
burst of brown waters wrapped round the dust of a prolonged
drought leaped the channels of the Concho Rivers here yesterday,
hurled to destruction an approximate of 300 houses in all
parts of town and left an uninsured flood damage of abut $1,500,000,
the worst water damage in the history of this 68-year-old
city. It is the major catastrophe of all time for San Angelo.
More than 100 persons were rescued from drowning on the streets
or from flooded houses, while many hundreds more were removed under
conditions less dangerous. There was an estimated 300 homeless families
last night, who were sleeping in the schoolhouses and in other public
buildings, in stores, while hotels were filled. Numerous buildings
not destroyed were flooded and filled with silt.
The North Concho River, chief troublemaker of the day, charged
drunkenly into the Negro and Mexican section, threw houses
and shacks against the Sixth Street Bridge now under construction
spread wanton piles of other wrecked houses here and there.
Then it moved into the elite residential district, climbed
a 40 ft cliff to run a stream knee deep in the home of Preston
Rothrup. It tore the C.R. Hallmark home from its foundations,
raced it over the Santa Fe Golf Course, and cracked it into
matchwood at the submerged Millspaugh Bridge."
SAN ANGELO EVENING STANDARD - SEPTEMBER 18: "Perhaps
the most dramatic episode of the flood in downtown San Angelo
was the evacuation of approximately 75 persons from the
Naylor Hotel, at Chadbourne and Concho, at mid-afternoon.
A crowd of at least 1,000 persons witnessed the rescues.
The water flowed 6 ft deep through the lobby of the hotel,
which stands on the site of the old Landon Hotel, destroyed
by fire. The 1906 flood had brought the water up to within
2 ft of the old Landon."
SAN ANGELO MORNING TIMES - SEPTEMBER 19 - "Rockwood,
Coleman County,—Hundreds of farmers and their families
were fleeing from the Colorado River bottoms near here tonight
as the river reached a flood stage of 70 ft, 17 ft higher
than ever known. The steel highway bridge at Stacy and the
one here went out this afternoon under the hammering of heavy
debris pounded against them by the turbulent flood.
Flood stage here is 35 ft. The previous high-water mark here
was set in 1906, when the river reached 55.5 ft long time residents
said."
SAN ANGELO STANDARD TIMES - SEPTEMBER 20: Brownwood, Sept
19—"The treacherous floodwaters of the Colorado
River late today claimed their second victim when a farmer
was drowned while attempting to save his livestock. The
angry river was 2 mi wide at Indian Creek community, in
Brown County, washing away a number of homes and barns.
The flood stage climbed to 72 ft where the Brownwood-Brady
Hwy bridge crosses the Colorado. This mark is 14 ft higher
than any ever recorded before."

1948 - Tropical air from the Gulf streamed into the
Devils/Pecos area several days before a 700-mb trough in the
westerlies moved into the Dry Devils drainage above Loma Alta
near 3 AM the morning of June 24, 1948 - Heavy rainfall moved
northwest to southeast into the prevailing low level flow,
indicating a mesoscale convective complex was set up with
the first thunderstorms in the early morning hours - then
the storms built into the oncoming low level jet from the
Gulf through the day.
There were three rainfall centers - The first heavy rain
(24.0 in.) was in the early morning hours until daybreak in
the upper end of the Dry Devils drainage - The second between
the lower Devils River and the Sycamore Creek drainages at
Wardlaws Ranch of 28 in. during the morning daylight hours
- And a third between the Sycamore and Pinto Creek drainages
of 36.0 in. during the afternoon.
The river float gages hit the top of the gage houses at
San Felipe Creek and the Rio Grande at Eagle Pass - Crests
were obtained from high water marks - The flow at Eagle Pass
rose to the IB&WC cable way seat and wrecked it - Downstream
at Laredo the flow again reached the top of the IB&WC
cableway. The floodways were activated above Brownsville/Matamoros
and saved the cities from disastrous flooding.
Del Rio - Two persons drowned, 6 homes were destroyed, and
20 had major damage Eagle Pass - flow was 4 ft over the deck
of the International Bridge, and much of the residential and
business area between the river and downtown section flooded.
Laredo - flow was 2 ft over the International Bridge floor.
Flooding was severe in the blocks adjoining the river, and
flow backed up Chacon and Zacate Creeks.

1952 - Sept 11, 1952 - In the middle of the 6-year,
worst in Texas history drought (1950 - spring of 1957), two
disastrous floods occurred - One in Sept 1952 on the Pedernales
and Guadalupe Rivers, and the other in June 1954 in the Devils/Pecos
River and Rio Grande drainages.
Sept 1952 was after the El Nino winter of 1951-52 - There
was no tropical activity in Texas the year of 1952. The Hwy
281 bridge at Johnson City on the Pedernales River was washed
away and destroyed. Major flooding also passed down from the
mid Guadalupe River.

1954 - Hurricane Alice formed as a tropical depression
in the Bay of Campeche the early morning hours of June 24,
1954 - grew to hurricane intensity the afternoon of the 24th
and made landfall 20 mi south of Brownsville late morning
of the 25th. The system moved directly up the Rio Grande Valley
before falling below depression intensity in the Devils/Pecos
area the afternoon of the 25th.
Characteristic of Texas tropical systems - this one was most
deadly at the stage it became dormant dynamically - It entered
the "Core Rain" phase the evening/early morning
hours of the 26th/27th. The Tom Everett Ranch on the Pecos
River near Pandale and the Vic Pierce Ranch in Government
Canyon between the Pecos and Devils River drainages, each
received 35-in. centers in 36 hrs. The heavy rain was widespread
over the Devils/Pecos area.
The first 35-in. center at the Tom Everett Ranch produced
a crest of 1,050,000 cfs on the Pecos River at Pandale - Downstream
near Comstock, 5.5 mi above the Rio Grande confluence, the
first crest was at 7:30 AM 6/27, 82.0 ft, 695,000 cfs. The
second crest was 1:30 AM 6/28, 96.24 ft and 948,000 cfs. It
is estimated that 940,000 cfs of this crest was produced by
the 3,504 mi2 of Pecos drainage below Sheffield
- 268.26 cfs/mi2 over a major river drainage is
a very large runoff rate.
The Devils River crested at 5:00 PM 6/28 at 34.76 ft, 585,000
cfs at Pafford Crossing 4.5 mi above the Rio Grande confluence.
The two crests (Devils and Pecos) would be out of phase entering
the Rio Grande thankfully, but still produced a crest of 1,140,000
cfs at Del Rio.
The crest was at 5:00 AM 6/29 at 53.51 ft, 964,000 cfs downstream
at Eagle Pass. Flow was to the heads of parking meters in
downtown Eagle Pass, and the International Bridge was destroyed
as flow was near 10 ft over the floor - The Southern Pacific
railway bridge over the river was destroyed, and much of Piedras
Negras on the Mexican side was underwater with a tragically
high number of drownings. The river was 3 mi wide at Eagle
Pass; Eagle Pass and Piedras Negras line the river.
The crest at Laredo was 61.35 ft, 717,000 cfs, at 9:30 AM
6/30. Flow covered over 200 city blocks of Laredo and a like
number in Nuevo Laredo. Flow went through the Mexican customs
building in Nuevo Laredo. Houses and businesses flooded miles
from the Rio Grande as flow backed up Chacon and Zacate Creeks.
Flow was 15 ft over the International Bridge.
A fortuitous side of the event occurred downstream at Falcon
Reservoir. The reservoir was completed in October 1953, and
the gates closed to begin impounding water. In this very severe
drought period, the reservoir was practically empty going
into the June 1954 flood. The lowest elevation before the
flood was June 16 at 252.11 ft, 377,700 acre-ft - conservation
level 301.2 ft, 2,440,000 acre-ft.
The inflow crest was 528,000 cfs at 3:00 AM July 1, 1954.
Within 3 days after the onset of the flood wave, flow was
approaching conservation level from a near-empty reservoir
- a level hydrologists had predicted would take 3 to 4 years.
The crest elevation would be an elevation of 292.94 ft, 2,179,300
acre-ft, July 18, 1954, the first time releases exceeded inflow.
1957 - April-May-June - That spring Texas was caught
between an abnormally strong Bermuda high which extended into
the eastern Gulf of Mexico, and a persistent long wave trough
over the western U.S. - Maritime cool fronts periodically
pushed across the Central Plains but didn't move into central
Texas shutting off the Gulf and eastern Pacific moisture -
Upper lows persistently moved around the south periphery of
the long
wave into Texas, bringing eastern Pacific moisture with them
into the low-level jet off the Gulf flowing into central Texas.
All of north-central, northeast Texas, much of Oklahoma,
Arkansas, and Louisiana had 20 to 36 in. of rain in April-June.
Most bridges on the Brazos River washed out in this long lived
flooding period.

of Lampasas between 6:00 and 10:00 PM May 12, 1957, put nearly
all of Lampasas underwater. A downtown restaurant today on
Hwy 281 still notes the crest with a high-water mark on the
front door about 5 ft from the floor.
Flooding was catastrophic as torrential flow slammed through
stores, public buildings, and homes in the evening hours with
terrific force. Autos were washed about like wood chips, and
homes were destroyed. Extremely severe damage to homes, commercial
and public property covered 68 city blocks. Four-hundred thirty
families had losses to residences, of which 50 were totally
destroyed. One-hundred sixty-eight businesses suffered major
damage.
Five persons drowned - four in Lampasas, and one in Gunderland
Park, a privately owned recreational park 2 mi below Lampasas.
Ten flood-retention dams in the headwaters of Sulphur Creek,
on Pillar Bluff, Espey, Pitt, Hughs, Donaldson, and Burleson
Creeks west of town, constructed by the Natural Resources
Conservation Service (NRCS) has prevented a repeat of the
above disaster. Many flood prone communities across Texas
have had flooding greatly diminished by NRCS retention dams,
I.e., San Marcos and Boerne.

Sept 2, 1967 in the Atlantic just past the Virgin Islands
- reached hurricane intensity as it moved into the Caribbean,
and spent 2 weeks moving across the Caribbean and western
Gulf before making landfall at Brownsville the morning of
Sept 20, still at hurricane intensity. Residents of Falfurrias
were evacuated as the track continued to the northwest as
it moved inland. As the hurricane passed to just south of
Alice, residents of Falfurrias began moving back in their
homes. Then in the early morning hours of the 21st, the hurricane
reversed its course and began moving south-southwest toward
Mexico. Residents of Falfurrias were quickly evacuated a second
time in the early morning hours.
As the hurricane lived 2-1/2 days over land, it spawned 11
rainfall centers over 20 in. between Victoria, Tex., and the
Sierra Madre Oriental mountains of northern Mexico. There
were four centers of 30 in. or more. Many south Texas streams
still record the runoff from that event as their historical
record flow.
The very warm, saturated, large tropical air mass spawned
115 tornadoes as far as Houston and Austin. Hwy 77 at Sarita,
the main artery between Corpus Christi and Brownsville was
closed 6 weeks by flooding. Goliad had homes flooded as the
San Antonio River crested just at the south edge of downtown.
The Hwy 59 bridge over Coleto Creek west of Victoria and the
Hwy 281 bridge south of Three Rivers were destroyed. Much
of the south Texas floodplain had several feet of sheet flow
over tens or hundreds of square miles.
The high-water mark in Three Rivers was very visible. The
town is built around an oil refinery. There was an oil ring
all over town 5 to 6 ft deep. Three Rivers is so named because
it is near the confluence of the Atascosa, Frio, and Nueces
Rivers.
Roads, bridges, fences, livestock, homes and businesses were
destroyed all over south Texas west of Victoria to the Rio
Grande.

1970 - May 14 to 15, 1970 - Heavy rain began in the
Sink, Purgatory, Limekiln, and Willow Springs watersheds near
San Marcos near 6:00 PM May 14, 1970. By 3:00 PM May 15, rainfall
would range from 6.0 in. at the Sink and Purgatory Creek headwaters
to 18.0 in. at radio station KCNY in downtown San Marcos.
The heaviest period was midnight to 6 AM of the 15th.
Disastrous flooding began after 8 AM and crested near 11
AM of the 15th. Four-hundred five homes were severely flooded,
and many more businesses and public buildings. Three elementary
schools were flooded, and students from one were rescued from
the roof by helicopter. Two children drowned when the small
aluminum boat they were being rescued in overturned.
The Aquarena Springs Administrative Building had 6 ft of
water in it. The National Guard was de-activated as their
facilities flooded. The armory had several feet of water in
it. Many hundreds of cars were washed about and destroyed
as tens of ft of turbulent flow covered many city streets.
Five flood-retention dams built by the NRCS prevented additional
severe flooding down these drainages. These structures prevented
much of the city from being destroyed recently in the October
1998 flood when 20 in. to more than 30 in. of rain fell over
the entire drainages.
1972 - May 11, 1972 - Heavy rain began falling over
eastern Comal County near 8 PM May 11, 1972, and by midnight,
a center of 16.5 in. was measured on the Guadalupe River exactly
halfway between New Braunfels and Canyon Lake Dam.
The first flood wave came down Blieders Creek, passing into
the Comal River at Landa Park in New Braunfels. The Comal
River gage at San Antonio Street at the Tube Chute Park crested
at 11:45 PM May 11 at 36.55 ft, 60,800 cfs from the Blieders
Creek flood. It would crest again at 5:30 AM May 12 at 35.45
ft, 55,800 cfs from the flood down Dry Comal Creek which heads
in the western part of Comal County.
The Guadalupe River above the Comal River confluence (at
Common St.) crested at 31.65 ft, 92,600 cfs probably near
12:30 to 1 AM May 12. The New Braunfels gage (at the "Factory
Mall") crested at 38.0 ft.
Residents and business owners were under the false illusion
that Canyon Dam, 20 mi upstream, would protect them from flooding.
This storm fit almost exactly in the Guadalupe River drainage
below Canyon Dam. Homes washed downstream in New Braunfels
and Seguin. Many homes were seriously damaged or destroyed
in the floodplains along Lakes Dunlap and McQueeney. Treasure
Island is an exclusive residential area built on an island
in Lake McQueeney. All the homes, probably over a hundred
very expensive homes, flooded.
Fifteen persons drowned, eight along the Comal River, and
seven on the Guadalupe in New Braunfels. Autos were washed
and stacked like cord wood.

1978 - August 2, 1978 - Tropical Storm Amelia formed
in the western Gulf of Mexico, southeast of Brownsville the
evening hours of July 30, 1978, never was officially raised
to hurricane intensity, and made landfall near Port Isabel
that evening.
As the system moved into the Texas Hill Country the evening
of July 31, it dropped below depression intensity, a very
dangerous phase in Texas flooding history. Showers and periods
of heavy rain began falling west and northwest of San Antonio
August 1st. Disastrous heavy rain fell the evening of Aug
1st/early morning hours of Aug 2nd.
Roland Manatt, in the Rocky Creek drainage along the divide
between the Medina and Guadalupe Rivers, 8 mi northwest of
Medina, measured 48 in. of rain in 52 hrs. He began measuring
in a vegetable can which rapidly became tiresome in the sometimes
over 4 in/hr intensities. He switched to a large fruit juice
can and stayed awake over 2 days and nights measuring the
rain. He said he dozed off a few times and let the can overflow
- so the 48 in. is to be considered a lower limit.
Charles Voss, in the same area, measured 42.0 in. during
the same period; Joe Ortiz 35.0 in.; Heneary Heinen 31.0 in.
The National Weather Service cooperative observer, John Derry,
the postmaster at Medina, measured 32.0 in. during 24 hrs
ending at 7 AM Aug 2nd.
This was another example of "Core Rains," as was
Hurricane Alice, and the 1921 Thrall storm. The heaviest rain
was during the early morning hours at the storm center. The
storm would drop a 32.5-in. center in 24 hrs near Albany in
north Texas ending at 7 AM Aug 4th.
During daylight hours, these tropical systems disperse into
scattered thunderstorms as solar radiation heats the top of
the air mass and stabilizes it. During nighttime hours, the
top of the tropical air mass cools and destabilizes it. The
instability entrains into a "core" at the center
of the system.
The Guadalupe River at Bandera crested at 46.62 ft Aug 2,
1978; 19 ft over the Hwy 173 bridge in Bandera. Disastrous
flooding also passed down the Guadalupe River below Hunt to
Canyon Lake. The Guadalupe River at Comfort crested at 40.90
ft, 240,000 cfs. Twenty-seven persons drowned in the Texas
Hill Country. Of these, only three drowned in automobiles.
The others drowned in their homes or trying to rescue cattle.
Nearly all were elderly (over 60) or young (under 12).
One example told by Mr. Thompson, the caretaker of Camp Bandina,
a Church of Christ recreational camp on the Medina River below
Medina - Warnings were issued and the people left their homes
beside the Medina River. A large flood wave passed through
and receded. A family of four in a Volkswagon bus returned
to their home to load belongings in the bus. They were loaded,
in the bus and ready to leave when they noticed they didn't
have their dog. As they got out to find the dog, a second
wave came down and swept all four downstream. The dog almost
certainly was on the bluff watching them as they were swept
downstream.
In all, eight persons drowned at Camp Bandina. Many homes
washed downstream at that site. Mr. Thompson participated
in the search afterwards and said the only way they found
some bodies was to look where buzzards were circling overhead.
An additional seven people drowned in Albany as Hubbard Creek
washed through town in the early morning hours. Many people
were picked from trees and saved.

1979 - Tropical Storm Claudette formed in the central
Atlantic the morning of July 15, 1979. It never reached hurricane
intensity as it wandered across the northern Caribbean and
the Gulf of Mexico 10 days, making landfall near Port Arthur
the evening of the 24th.
The storm veered left and stalled over Alvin the evening/early
morning hours of the 25th/26th. This was a weak tropical storm
and went through the "Core Rain" phase during that
period. An observer 3.2 mi northwest of Alvin reported 8.0
in. during 4 hrs - 19.0 in. during 9 hrs, 30 minutes - 32.25
in. during 13 hrs, 47 minutes - 42.0 in. during 19 hrs - and
a storm total of 45.0 in. during 42 hrs ending at 6 AM July
27th.
1981 - May 24, 1981 - Shoal Creek Flood - A mesoscale
convective complex formed over north Texas and southern Oklahoma
the evening hours of May 23 - during the night the outflow
boundary pushed through central and south Texas to the Gulf
Coastal Bend near 7 AM.
During the evening hours of May 24th, thunderstorms formed
west and north of Austin as a short wave trough moved through
central Texas ahead of a slower moving long wave and with
a frontal passage west to east across the area - Storm movement
was very slow.
An intense thunderstorm formed just west of Barton Springs
near 8 PM, and moved slowly north-northeast across the Colorado
River and up Shoal Creek into the upper Walnut Creek drainage
by 11 PM. Torrential rain fell between 8 and 11:30 PM in these
drainages.
The Shoal Creek drainage received 4 to 6 in. on the lower
half below Anderson Lane - and 6 to 10 in. on the upper half
above Anderson Lane between 8 and 11:30 PM. The Balcones Research
Center in the headwaters of Shoal Creek recorded a 1-hr intensity
of 4.44 in., a 1-1/2 hr total of 5.59 in., and a storm total
of 7.55 in. The headwaters of Walnut and Little Walnut Creeks
received 6 to 10 in.
Five-hundred fifty cars washed from six auto dealerships
along Lamar Boulevard near and below W. 6th Street. These
autos formed a damming effect on Shoal Creek above the Colorado
River and greatly increased flooding in the Shoal Creek drainage
below W. 12th Street. Over 5,000 cars were stranded around
Austin during the night. Many were washed down creeks, some
into Lake Austin in the West Lake Hills area from the south
side.
A dozen businesses were destroyed and hundreds of homes severely
flooded the length of Shoal Creek and much of Walnut Creek. A few
homes along Shoal Creek were knocked from their foundations by the
raging flow. Thirteen persons drowned, all in autos except two persons
along Shoal Creek who drowned trying to escape their home as the
flood wave slammed through.

1981 - Aug 30 to 31, 1981 - Halletsville Flood - A
minimal tropical depression made landfall just south of Brownsville
Aug 29, moved up the Rio Grande Valley to just east of Laredo
the AM of the 30th, veered north to just south of San Antonio
the evening of the 30th, and was near Seguin near midnight
of the 30th. The storm moved east north east to north of Houston
late afternoon, the 31st. An area of heavy rain 50 to 75 mi
wide and 200 mi long fell between Seguin and north of Houston,
as the center moved across.
Area rainfall: Cheapside 18.00 in., Hochheim 17.50 in., Gonzales
16.31 in., Moulton 9.00 in., Shiner 7.00 in., Geronimo 10.11
in., Muldoon 17.00 in., 3 SE Karnes City 16.29 in., Schulenburg
9.48 in.
Flow was 5 ft deep on the town square in Halletsville - Flow
came up so quickly near daybreak that some vehicles couldn't
be moved from the town square - Prisoners had to be evacuated
very quickly from the county jail - Ninety percent of the
business district and 70 percent of homes in Halletsville
flooded. Three young boys drowned along Rocky Creek when their
home was swept away in Shiner. Two men drowned in a low-water
crossing when their pickup truck was swept downstream near
Shiner.
This was disastrous flooding down the Lavaca and Guadalupe Rivers
- Major flooding down the Colorado River near LaGrange from heavy
flow down Buckners Creek.

1984 - Oct 19, 1984 - Odem Flood - An upper low moved
across the Rio Grande Valley at Laredo near 7 AM Oct 19th
with thunderstorms dropping centers to 2.50 in. - By noon
the low remained intact and had moved over Tilden, still with
isolated centers to near 2.50 in. - At this point the low
moved southeast and moved across George West near 3 PM, still
with intense thunderstorms, still moving 20 to 25 mph, still
dropping heavy rain centers - Texas was in an intense drought
from the summer of 1983 to that period, and the rain was good
news.
The lead forecaster at the San Antonio National Weather Service
Field Office, Larry Eblen, received two phone calls that evening
that the Nueces River was running from Calallen to Mathis
(upstream, uphill).
Intense rainfall and flooding reports became so severe and
observers so sparse in the area that the Corpus Christi weather
office issued a request over Corpus Christi radio stations
for people in the Odem-Sinton area to call rainfall reports
to the Corpus Christi office. One observer in Odem received
24.0 in. during 3 hrs, 45 minutes. An observer a block and
a half down the street received 25.5 in. during the same time
period - between 4:00 and 7:45 PM.
A railroad track in Odem acted as a low water dam until it
"breached" - Sheet flow about 3 ft deep flowed across
the coastal plain from Odem to Sinton, and rapidly put over
half of Sinton underwater. There were no fatalities, but one
disabled person was rescued in waist deep water.
The dynamics were strong low-level convergence between the
sea breeze and a weak front moving southward through the area.
The upper-level divergence was provided as the upper low moved
over the front at Odem and stalled because the mesoscale lift
and dynamics completely overpowered anything of a larger scale.
The rainfall was in a very tight center. Bluntzer, 12 mi west
of Odem received 23.0 in. Alice, 25 mi west of Odem received
.06 in., Beeville, 33 mi north .05 in., and the National Weather
Service at Corpus Christi, 13 mi south-southeast, .04 in.
This was a strange evening - The weather detachment at Randolph
Air Force Base, when asked of flooding problems, reported
only that their Air Police were picking up drowned ducks on
the base - When asked how a duck could drown, they reported
that the only thing they could come with was that the ducks
were looking up during the heavy rain (3.50-in. total) - Either
that or the Air Force was pulling the NWS's leg.
1987 - May 31 to June 13, 1987 - A long-wave trough
the first half of May extended from western Oklahoma and the
Texas Panhandle southwest across New Mexico into the Sonoran
Desert of Mexico. Eastern New Mexico (Hobbs and Carlsbad)
received severe flooding during the period.
By the latter week of May, the long wave had moved eastward
over west Texas. Upper lows moved around the southern periphery
and directly across central Texas. As these lows moved into
the confluence of the mid- and upper-level water vapor plume
off the eastern Pacific across Texas and the low-level jet
from the Gulf into central Texas, the upper lows intensified
tremendously. A series of these storms moved over the area
for 2 weeks (May 31-June 13), producing a series of major
floods.
The total flow volume down the rivers from the Brazos to
the Nueces Rivers totaled 8,800,000 acre-ft. Some superlatives
- A Texas DPS trooper was picked from his auto by a Texas
Mobile Army Surgical Transport (MAST) helicopter near 1 PM
where Leon Creek crosses IH-10 at the site of the current
Fiesta Texas theme park. Rescued in the same vicinity was
a TxDot worker from his truck. The flooding began upstream
just west of Leon Springs when children from a daycare had
to be rescued in waist deep water during the late morning.
The jet engine test facility downstream at Kelly AFB had 3
ft of water inside it by late afternoon. Several homes and
horse barns flooded along Leon Creek below Kelly AFB.
Canyon Lake rose to 942.64 ft on June 20, 1987 - and for
the first time had water flowing into the emergency spillway.
Flow didn't pass through the spillway (occurs at 943.0 ft)
but seeped part of the way across.
Medina Lake rose to 1,078.2 ft, 6.2 ft over the spillway
elevation of 1,072 ft. This put up to 4 ft of water in about
50 homes at the upper end of the lake at Whartons Dock and
Alamo Beach. Downstream, in Bexar County, homes and businesses
below LaCoste, near Von Ormy and Somerset flooded severely.
Thirty to forty homes in Seguin flooded from Walnut Creek,
a minor creek that flows into Seguin from the northwest. An
apartment complex just north of Hwy 90 had 2 ft of water in
it. A dozen homes flooded in D'Hanis, requiring some rescues
by helicopter from rooftops on May 29. Heavy rain fell again
on June 3, scaring people but not flooding homes.
In Tilden, the Frio River flooded many homes and businesses.
A well-known restaurant on State Hwy 16 at the Frio River
had 2 ft to 3 ft of water in it twice - June 5th and 9th.
A small amount of water also rose into the restaurant June
17th.
May 30th, up to 10 in. of rain fell in Las Moras Creek
above Bracketville in Kinney County. Six in. fell in an hour.
Las Moras Creek flooded much of the town with water up to
waist deep in some homes and apartments.
Flooding in the Guadalupe River was disastrous. In Gonzales, the
Guadalupe River backed up Tinsley Creek. As the creek moved runoff
down it, over the Guadalupe River back flow, homes flooded along
the creek in Gonzales.
At Cuero, Hwys 87 and 183 west and south of town were flooded
and closed. Near Thomaston, 10 mi downstream from Cuero, nearly
100 homes had up to 9 ft of water in them in the River Oaks,
River Haven, and Oak Haven subdivisions.
In Victoria, 20 homes flooded, and a 20-block area of the
west side was cut off. Fifty people had to be evacuated in
the Riverside Park and Greens Addition area. The city zoo,
park, and golf course were severely flooded.
The San Antonio River at Goliad completely submerged recreational
areas of Goliad State Park, and water was within inches of
closing the Hwy 183 bridge.

1987 - July 17, 1987 - Bus Tragedy Flood - During
the mid-evening hours of July 16, 1987, an upper low moved
out of Mexico, across the Rio Grande south of Del Rio, moving
east-northeast into Texas. As the low moved north of Bracketville
at 20 to 30 mph, an observer reported a rainfall total of
6.00 in. The upper low disappeared from radar and satellite
displays as it moved into Real County.
A very weak cool front (middle of July) was moving south
through Junction during the evening hours of July 16. There
were no temperature contrasts, just dewpoint differences.
The upper low made itself known as it moved into western Kerr
County in the form of very heavy rain in the headwaters of
the North and South Forks of the Guadalupe River at 11:45
PM June 16. By 4:30 AM June 17, there would be an 11.0-in.
rainfall center at Mo-Ranch, 10 mi west of Hunt.
There is an unofficial river network on the upper Guadalupe
River. Boss Merritt lives in the headwaters of the South Fork.
At 1:30 AM he was concerned enough by the rapidly rising flow
to dangerous conditions that he began calling the recreation
camps below him. Dick Eastland, manager at Camp Mystic, received
a call and he and his staff began moving canoes, life jackets,
and gear from their docks. By 1:45 AM the flow was so high
they abandoned the docks and rushed to higher ground.
Downstream, 2 mi above Hunt, Ron Duke had built a house on
stilts on the left bank of the South Fork, about 50 yards
from the river. He went to bed that evening with his pickup
parked beside the pilings supporting his home 20 ft in the
air. A banging awakened him at 2:30 the morning of the 17th.
He rushed outside on his deck and fell through the partially
missing deck into the Guadalupe River. Ron was able to pull
himself back onto his deck. The banging was the sound of his
pickup against the pilings 19 ft above the ground. The river
would continue rising to 1-1/2 ft above the deck before it
began receding.
Firefighters were not able to get to him because Hwys 27
and 39 were flooded in many places. As the water receded,
a ladder truck was able to get to his home and shoot a ladder
horizontally from Hwy 39 to his deck.
Flooding was widespread along the North and South Forks in
the recreation camps, roads, and bridges. Most camps flooded
severely with many ft of water in them.
However, no lives were lost in the headwaters as the Guadalupe
River at Hunt crested at 28.4 ft (flood stage 12 ft) at 4:30
AM. The fatalities would occur 30 mi downstream near Comfort.
Three hrs later at 7:40 AM, a church group from Balch Springs
near Dallas was scheduled to leave to return home. The assistant
pastor, Mr. Koons, made the decision to leave.
The caravan was led by a pickup truck driven by the Pot O'
Gold Baptist Church Camp caretaker, Mr. Roy Harris. Second
was a school bus, and third, a van. As Mr. Harris drove through
the gate leading out of the property, he did not see any water
anywhere. By the time he had driven 200 to 300 yards, he had
1-1/2 ft of water over the bottom of his pickup. The school
bus made it about 75 yards from the camp gate to where it
should have crossed a cattle guard and turned left away from
the river onto a farm-to-market road. The school bus stalled
at this point (the cattle guard) from the high water and trapped
the van behind it.
Mr. Koons, driving the bus, deliberated for seconds and ordered
the kids to leave the bus and try to make it the 75 to 100
yards back to a ridge where the gate they had just passed
through was. None made it. They were all washed downstream
through the trees and barbed wire fences. Within 2 hrs, 15
DPS, MAST, and news helicopters were circling within a 1-mi
radius. Of the 43 kids and counselors washed downstream, 10
drowned. One young man washed onto a deer hung in a barbed
wire fence. As the boy grabbed the deer, he freed it, and
the deer pulled him to shore. Another young man was never
found.
The media intensity was extreme the next day as they descended
on the youth pastor who made the decision to leave that morning.
The group was exactly at the wrong place at exactly the wrong
time. A few seconds earlier and they escape the worst of the
flood wave. A few seconds later, and they see the floodwaters
and don't drive into them. The flood wave didn't come at the
group directly from river at their site. It escaped the river
channel upstream and came down an old historical channel and
"flanked" them from the left.
On behalf of the 43 kids, only three lawsuits were filed.
A dispute arose as these three families sued the church camp
and the Kerr County Sheriffs Department. The church camp said
they weren't notified of the flooding. The Sheriffs Department
said a call was made to the camp at 2 AM and again at 6 AM
that morning. The incident was at 7:40 AM. The NWS issued
the first Flash Flood Warning at 1:45 AM and the first river
Flood Warning at 2:30 AM. The litigation was settled out of
court and the results not made public.

1989 - May 17 to 18, 1989 - An upper trough oriented
southwest to northeast moved slowly across central Texas the
early and mid-morning hours of May 17. By evening of the 17th,
the trough was dropping heavy rain in a band from eastern
Harris County to the upper end of Toledo Bend Reservoir as
the trough stalled and set up "train effect" rainfall.
Thunderstorms were moving at 20 to 25 mph, but training over
the same area for 12 hrs ending 7 AM May 18th. Some totals:
Houston Intercontinental Airport 10.36 in., Conroe 13SSE 13.10
in., Tomball 7.41 in., Conroe 5 SW (Woodlands) 8.00 in., New
Caney 11.89 in., New Waverly 9.20 in., Cleveland 12.83 in.,
Liberty 14.00 in., Batson 12.00 in., Thicket 11.00 in., Kountze
9.20 in., Kirbyville 6.32 in., Warren 6.00 in., Woodville
13.40 in., Orange 10.00 in., Port Arthur 9.30 in., Bridge
City 15.00 in.
Toledo Bend Reservoir and Lake Houston both reached record
elevations. Toledo Bend was releasing 30,000 cfs of flow through
the gates going into the event as they already had a high
pool. With the 10.0 to 17.0 in. directly on the drainage into
the upper end of the lake, water rose extremely quickly in
the reservoir to a record level of 173.90 ft by midnight May
18, previous record 173.42 ft.
Record flow was observed below the dam at Burkeville. Gage
readings by the regular satellite telemetry were doubtful,
so a USGS technician left Houston, crossed the Sabine River
downstream at Orange, drove up the Louisiana side to Burkeville
and waded through 1 to 2 ft of water to get out to the bridge
and read the wire weight. The river gage indicated a crest
of 48.90 ft, but the wire weight reading was only 47.45 ft
- still a flood of record, exceeding the previous record of
44.20 ft Sept 14, 1967.
Nearly a hundred homes flooded in the River Road housing
subdivision just below Toledo Bend Dam on the left bank. Water
was to the roof of one two-story home. Several additional
homes flooded downstream at Deweyville.
Hundreds of homes flooded on Cypress Creek and the West Fork
of the San Jacinto River above Lake Houston, some to 6 ft
inside the homes. Lake Houston crested at a record 49.60 ft,
above the 49.43 ft of April 1979. Thousands of homes flooded
in the Banana Bend and Highlands floodplains of the San Jacinto
River below Lake Houston. Hundreds of homes flooded and thousands
of people were evacuated along Greens Bayou in Houston and
Peach and Caney Creeks in Montgomery County. Over 400 people
were evacuated in Liberty County, and hundreds of homes flooded
as the Trinity River was 10 mi wide between Liberty and Dayton.
Bevil Oaks, in the Pine Island Bayou drainage, had 11 homes flood.

1991 - Dec 18 to 23, 1991 - Christmas Flood - A stalled
long wave Dec 18th over Arizona extended into the Sonoran
Desert of northern Mexico. The upper low was reflected at
the surface along the Arizona/Mexico border. A series of cold
air masses pushed from the Pacific Northwest across the Central
Plains into the southeastern U.S.
A cold-air-induced surface high was centered over Georgia.
A stationary front in central Texas marked the southern periphery
of the cold air masses moving across the Central Plains. At
low levels, clockwise flow around the southeastern high brought
a long fetch of very warm moist air across the Gulf, across
the Texas Coastal Bend, and into central Texas as a low-level
jet. The weather station at Corpus Christi measured 850 mph
winds of 60 to 70 knots from about 160 to 170 degrees for
the duration of the storm. The low-level jet slammed into
the stationary front across central Texas as a trigger mechanism.
At upper levels, the long wave in the west induced a water
vapor plume from the eastern Pacific across Mexico into Texas.
Tremendous rain and flooding occurred at and south of the
confluence of the upper vapor plume, the low-level jet, and
the surface stationary front. The heaviest rain was 16 to
18 in. on an area from Llano to Bandera to Boerne. The 6-in.
isohyetal extended from the Red River north of the Dallas/Fort
Worth metroplex - to near Coleman - to between Bracketville
and Uvalde - to near Corpus Christi - to near Palestine -
to the Red River.
This was not a historic event in terms of large rainfall
totals. But in terms of total rain volume that fell from the
sky in one event, this certainly was one of the largest in
Texas recorded history, if not the largest. Certainly it rivals
Hurricane Beulah, the June 1935, Hurricane Alice in 1954,
and the June 1987 floods.
Record flooding moved down the San Gabriel and Little Rivers
into the Brazos River above Bryan. The Brazos River was 5
mi wide west of Bryan and College Station. The Navasota River
was well over 1 mi wide in Grimes and Brazos Counties. A huge
lake over 10 mi long by 10 mi wide was created above the confluence
of the Navasota and Brazos Rivers above Washington on the
Brazos State Park. High areas were above the water, but most
areas flooded.
Downstream, the Brazos River and Oyster Creek merged as the
Brazos River flowed over the left floodplain near Harris Reservoir.
Thousands of previously unsuspecting home owners were flooded
as Oyster Creek became several miles wide in Brazoria County.
Residential flooding was widespread above Simonton to the
Gulf in Fort Bend and Brazoria Counties. In the Valley Lodge
Subdivision near Simonton, most of the 200 homes flooded,
some a half mile from the river. Five-hundred homes suffered
serious flood damage in Brazoria County. Two-hundred forty-five
of 250 homes flooded in Holiday Lakes Estates between East
Columbia and Angleton.
Flooding was disastrous also in the Colorado River drainage.
Very high flows down the Pedernales and Colorado Rivers into
the Highland Lakes system put a tremendous amount of storage
into them. The problem was, managers could not release water
from Lake Travis because disastrous floodwaters were flowing
from Walnut, Onion, and all the other creeks flowing into
the Colorado River below Lake Travis. Onion Creek at Hwy 183
crested at 30.50 ft, a record since a recording gage was installed
March 1976. The Pedernales River severely flooded and damaged
LBJ National Park at Stonewall. Flow just seeped over the
stone wall at the Johnson Family Cemetery.
The Lower Colorado River Authority could do nothing but store
all the very high inflow. Lake Travis quickly rose to a record
elevation of 710.44 ft Dec 26, 1991. Nearly 400 homes flooded
around Lake Travis with up to 22 ft of water over the lowest
slabs.
Downstream, a few homes flooded near Bastrop as the Colorado
River crested at a record 37.48 ft. Between Bastrop and Smithville,
the Hidden Valley Estates, the Doty River Estates, and the
Pecan Shores subdivisions had several tens of homes flooded
up to nearly 9 ft. In LaGrange, the Fritsch Auf subdivision
had over 10 homes flooded up to 6 ft.
Two homes flooded in Columbus. Downstream, 15 homes flooded
up to 2 to 3 ft in Wharton. Much worse flooding was spared
because the flooding escaped over the left floodplain upstream
near Garwood into a widespread area of farmland.
The Guadalupe River had severe flooding. Two homes flooded
near Cuero, and downstream near Thomaston in the River Haven
subdivision, three homes flooded.
In Victoria, eight city blocks of the Greens Addition in
the west part flooded, and also the city park, zoo, and golf
course. Downstream, the Guadalupe and San Antonio Rivers were
several miles wide near their confluence near Tivoli. Some
ranchers would feed their cattle by boat on floodwaters into
June.
1991 was an El Nino year. This flood would be followed by
a series of floods a week or 10 days apart into late May or
early June. Emergency spillways on every flood-control reservoir
on the Brazos River would be spilling 2 to 3 ft by mid-March.
Water stood in the fields between storms from late December
into early June in many areas, mainly in the Brazos and Colorado
River drainages below Austin to the Gulf.
The Edwards aquifer would crest at a record 703.2 ft elevation
June 14, 1992.

1993 - May 5, 1993 Cinco de Mayo Flood - An upper
low or "disturbance" moved north-northeast into
south Texas around a long wave trough over the western U.S.
By 7 AM, the disturbance had formed a closed low aloft as
it moved into Bexar County. There were two "spiral bands"
around it. The cold-core low would change into a warm-core
tropical-like system through the day as it spit out up to
over 8 in. of rain in San Antonio. The upper low stalled over
San Antonio, and two spiral bands moved through the city during
the day, much as a "mesoscale" hurricane.
The first band went through the southeastern part of Bexar
County and dropped over 4.0 in. between 8:30 and 10 AM. A
man washed from Broadway Street near the Austin Hwy into the
San Antonio River and drowned. Autos were flooded in parking
lots, and streets were rivers. A second band moved through
northern San Antonio between 1 and 4 PM, dropping another
4 in. over some areas. Woods of Shavano wound up with 8.03
in., most in the afternoon.
Several blocks of homes in northern San Antonio flooded due
to poor drainage in the minor creeks through the area. An
elderly couple drowned where Elm Creek crosses Lockhill-Selma
Street as their car was swept downstream. Downstream, Olmos
Creek put several inches of water in the HEB Supermarket at
West Avenue and NE Loop 410. Several other businesses in that
shopping center flooded.
Salado Creek crested at a record elevation, putting a few
businesses in the Los Patios shopping center above Loop 410
underwater. Flow was within 6 in. of flooding the NE Loop
410 bridge floor. Most of a KOA Campground downstream on Gembler
Street was evacuated.

1994 - Oct 18, 1994 - The remnants of Hurricane Rosa
moved across south Texas very rapidly on the 15th, and caused
no flooding problems. Behind Rosa, precipitable water was
in excess of 2.00 in. over much of south and southeast Texas
on the 16th. A surface high over the southeastern U.S., coupled
with a surface low over Colorado, was producing a strong low-level
jet into south and southeast Texas.
There was pronounced upper-level diffluence at 300 mbs over
the eastern part of south and southeast Texas. A warm front
sagged north during the day on Oct 15 from between Austin
and San Antonio to between Victoria and Houston. Intense thunderstorms
formed near the warm front the afternoon of the 16th and continued
through the night. As they built into the steering winds,
they advected north-northeast, and a large area from LaGrange
to Schulenburg to east of College Station received over 9.00
in.
The most intense rain was the night of Oct 17/18. Edna received
19.00 in. overnight and water was over the hoods of cars on
Main Street from flooding down a minor creek through town.
Southwest Montgomery County, near Magnolia and Montgomery
received over 30 in., and a second center near Cleveland also
received in excess of 30 in. Much of the area from Edna to
near College Station to Cleveland received over 15.00 in.
These were tropical rainfall events, heaviest at night during
the early morning hours.
Disastrous flooding passed down Cypress and Spring Creeks,
the West and East Fork San Jacinto Rivers, producing a record
elevation in Lake Houston by nearly 3 ft. Three-hundred forty-thousand
cfs passed over the emergency spillway down the San Jacinto
River below Lake Houston. The Houston Chronicle listed 15,775
homes damaged - 3,069 destroyed - 22 flood-related deaths
along these streams. Some homes flooded to the roofs of the
second story.
A notable characteristic of this flood was the widespread
heavy almost uniform rain of disastrous proportions, over
15 in., that produced major flooding and sheet flow in areas
well away from streams.

1995 - May 29, 1995 - Sandy Creek Flood - Much of
the month of May, an upper trough/low pressure area remained
over the inter-mountain area of the West. The upper divergence,
cool air at upper levels, and jet stream produced instability
and storms over the Central Plains.
By May 27th, the cool air mass/upper low began to migrate
eastward across the Central Plains to central Missouri by
7 AM of the 30th. The low dragged a cool front that pushed
through Texas to offshore by 7 AM of the 29th.
The 7 AM daily weather maps show an upper trough well northwest
of the surface front, with the trough axis extending from
the Texas Panhandle southward to the Del Rio area. Pronounced
diffluence was evident ahead of the trough in central Texas.
The heavy rain of the evening of the 29th was associated with
the passage of this trough. Central Texas was unstable the
night of 28/29 and also 29/30.
The heavy rain began in the evening hours of the 28th when
northwest Webb County received generally 5 in. of rain, extending
southward into Mexico. A 12-ft crest on the Rio Grande in
Mexico put 4 ft of water in lowest areas of the U.S. Customs
parking lot.
During the late evening hours of the 29th, the southern part
of Williamson County measured 6 to 8 in. of rain. Taylor received
4.10 in. Four homes flooded south of Taylor. Southward in
Travis County, Pflugerville received 5 in. between 11 PM and
1:30 AM of the 29th. Three homes flooded along Wilbarger Creek,
and 10 cattle drowned farther downstream. Several transients
were rescued from sleeping under bridges along Waller Creek
and other creeks in Austin.
Intense thunderstorms formed to the west in Mason County
and drifted slowly west to east across Llano and Gillespie
Counties. Between 8 and 11:30 PM of the 29th, the thunderstorms
would drop generally 4.5 to 5.5 in. of rain over the Sandy,
Crabapple, and Walnut Creek drainages. The maximum was 8.00
in. at Oxford. Sandy and Crabapple Creeks flow west-southwest
to east-northeast. As the thunderstorms generated flood waves
down these creeks, their movement west to east caused intense
rain on and ahead of the flood waves as they moved down Sandy,
Crabapple, and Walnut Creeks, exacerbating the crests.
Another factor was the uniform heavy rain over all the drainages.
All the drainages received over 3 in., and nearly all the
drainage received over 4 in. in nearly 3 hrs. The Sandy Creek
near Kingsland gage at Hwy 71 crested at 31.50 ft (127,400
cfs) at 12:15 AM of the 30th.
Downstream, is a housing development, Sandy Harbor, at the
confluence of Walnut and Sandy Creeks, where Lake LBJ normal
elevation backs into the area. Very large flood waves down
Walnut and Sandy Creeks were confluent at Sandy Harbor, putting
water to the roofs of several homes by shortly after midnight
of the 30th. One couple was trapped in their home and stood
on their dining room table to escape the water. The flood
reversed and began falling 6 in. from their ceiling.
Homes were flooded and businesses destroyed the whole way
to Sunrise Beach at the mouth of Lake LBJ, 2 mi below Sandy
Harbor. An extensive marina at Lake LBJ was washed away and
destroyed, as well as a large floating restaurant.
Sixty mi to the southwest, 2 to 3 in. of rain fell during
the early morning hours of the 30th. The Guadalupe River above
Comal at New Braunfels, the closest gage above Gruene, crested
at 7.34 ft near 5 AM of the 30th (6,710 cfs). This small rise
washed two vehicles downstream from the bank of the Guadalupe
River near Gruene.
One young lady was sleeping in a sleeping bag when it began
raining during the early morning hours. She got into her pickup
truck and was resting when it began floating downstream. Firemen
rescued her from a tree later. Her pickup was destroyed. In
another incident, a father, mother, and two daughters were
sleeping on the bank. According to the mother, the two daughters
began floating downstream on their air mattresses before they
all became aware of the danger. They survived, but lost all
their camping gear and their pickup was totaled. The mother,
from Texas City in the Houston area, was indignant because
signs weren't posted warning of the flooding danger.
1996 - October 28, 1996 - A major El Nino episode
would be officially declared by the Climate Prediction Center
the following March 1997. An upper low had made landfall in
British Columbia the 22nd and had slid down the West Coast
to the Sonoran Desert of northern Mexico/southern California/Arizona
the morning of the 27th. The closed low at that position forced
a water vapor plume at mid and upper levels across Mexico,
across Texas, into the Central Plains. There was marked diffluence
at upper levels over west Texas.
High surface pressure over Georgia and South Carolina coupled
with the Sonoran upper low forced a low level jet with a long
fetch over the Gulf into central Texas. At 7 AM of the 27th,
a surface cold front sagged across west Texas from Childress
across Midland. By 7 AM of the 28th, the front had moved to
a San Antonio - Texarkana line.
The heavy rain ended as an upper low over New Mexico, moving
around the "anchor" low to the west, kicked out
to the northeast on the 29th. This broke the upper-level tropical
plume from the eastern Pacific. This seems to be a frequent
model for heavy rain in Texas with major El Ninos.
The heavy rain was widespread between 6 PM of 10/27 and 12
noon 10/28. Heaviest amounts reported were 12.0 in. near Harper
in the headwaters of the Pedernales and also the James Rivers,
Rocksprings 11.00 in., Kickapoo Caverns north of Bracketville
11.00 in. Unofficially, amounts over 20 in. were reported
after the flood in western Edwards County. The heavy rain
began the evening hours of the 27th, in Kerr and Gillespie
Counties, over 200 mi ahead of the surface front north of
Abilene at the time.
Pre-frontal convergence, upper diffluence, and precipitable
water totals over 2.00 in. were enough for very intense rain,
without the frontal "trigger." Firemen in Kerrville
reported the Guadalupe River rose 8 ft in 18 minutes during
the evening at Center Point from reading their flood alert
system.
There was no river gage on the James River, but the South
Fork of the Llano River was 20 ft and rising by 7:30 AM of
the 28th. Flooding down the Llano River was devastating where
the Llano enters Lake LBJ at Kingsland. Recreation camps,
boat docks, boats, homes, and businesses were damaged or destroyed
at Kingsland and along Lake LBJ.
Kingsland Lodge, on the east bank of Lake LBJ, opposite where
the Llano River enters it, had several buildings seve |
