| Central Texas |
| June 30 to July 2, 1932 |
| Heavy rain June 30-July 3 on parts of the Nueces
and Guadalupe River Basins produced historically significant
peak discharges at several streamflow-gaging stations. Very
heavy rain fell on the upper Guadalupe River Basin west of Kerrville
June 30-July 2. This rain amounted to more than 35 in. during
about 36 hours at the State Fish Hatchery above Ingram. Heavy
rainfall also was recorded in the Frio and Medina River Basins.
Rainfall of 14 in. was measured at Bandera, Lima, and Medina
in the Medina River Basin. Vanderpool, at the headwaters of
the Medina River, measured 33.5 in. July 1-2. The floods in
the Frio River were the highest known at that time. The heaviest
rainfall on the Frio River Basin was at Rio Frio in Real County,
where 24 in. was recorded July 1-2. read

storms produced flash floods across seven counties north and northwest
of San Antonio. Heavy rains in Kerrville began at 4:00 a.m., and by
dawn 3.3 in. had fallen. As much as 11.50 in. of rain fell at Hunt,
with 5-10 in. on surrounding areas. read more... |

| June 30-July 7, 2002 |
| On June 30, 2002, a low-pressure
system migrating westward from Florida combined with a flow
of deep tropical moisture from the Gulf of Mexico and moved
over southern Texas. The system hit a wall of high pressure
and stalled over the central and south-central parts of the
State. For 8 days, the storm system continued to draw moisture
from the Gulf, which triggered several massive storms throughout
much of the area. As much as 35 in. of rain fell during the
event, with heaviest depths occurring in the Texas Hill Country
northwest of San Antonio. Flooding affected about 80 counties
in Texas.
Heavy rain also fell in parts of West Texas, including Abilene,
where 12-14 in. of rain in the pre-dawn hours of July 6 caused
flooding that required numerous evacuations. Heavy rains also
caused Lake Brownwood to overflow, causing evacuations and
flooding in parts of Brownwood.
The floods caused 12 deaths and damage to about 48,000 homes.
Nearly 250 flood rescue calls were reported, more than 130
roads were closed, and thousands of homes and businesses lost
electrical power and telephone service. Twenty-four counties
were identified by the Federal Emergency Management Agency
(FEMA) as Federal Declared Disaster areas—14 counties
were eligible for individual assistance and 10 counties for
individual and public assistance. Emergency management representatives
had not yet assessed the total cost of damages.
The storms produced large volumes of runoff and as many as
four flood peaks at each of many streamflow-gaging stations
in the Brazos, Colorado, and Guadalupe River Basins. Record
flood stages occurred at sites on the Medina River, San Antonio
River, Sabinal River, and Nueces River. For the first time
since it filled in 1968, Canyon Lake (northeast of San Antonio)
poured over its spillway, adding to the flooding in the Guadalupe
River. Emergency managers also were concerned about the 90-year-old
dam at Medina Lake (west of San Antonio). Medina Lake topped
its spillway and rose to within 18 in. of the top of the dam.
Areas downstream from the dam were evacuated as a precaution
because of the fear of dam failure. |
|
| Deaths and Damage: |
Twelve deaths occurred during the flooding and damage was
estimated to be about $1 billion. |
| Max. Precipitation: |
35.00 in. |
