Update
Trinity River Authority Curtails Release from Lake
Livingston Dam
Livingston, Texas-The
Trinity River Authority has decreased water releases
from Lake Livingston to 10,000 cubic feet per second
down from 20,000 CFS yesterday. Releases are
expected to further decrease to 1,000 CFS later
today.
TRA began releasing water from Lake Livingston on
Saturday, September 24, 2005 to lower the lake’s
water level after the dam’s earthen embankment was
damaged by sustained high winds and wave action
brought on by Hurricane Rita.
TRA released 79,200 cubic feet per second on
Saturday and Sunday which caused flooding in
low-lying areas downstream from the dam. On Monday,
releases were decreased to 20,000 cubic feet per
second.
The lower lake level will eliminate any further
erosion and allow TRA’s engineers to make a thorough
assessment of the damage caused by the wind and
waves and develop a remediation plan. The lake
level will be lowered to 127 feet above mean sea
level until repairs are complete.
Lake Livingston Dam is a 2.5 mile earthen embankment
with 12 tainter gates for releasing water. The
earthen embankment is protected from water erosion
by rip rap, large 32 inch diameter stones, on the
lake side of the dam.
The high winds and significant
wave action brought by Hurricane Rita damaged the
dam’s earthen embankment eroding approximately
11,000 feet of the rip rap on the lake side of the
dam, and exposing part of the earthen embankment.
Some erosion to the earthen embankment has also
occurred.
After a thorough inspection, Lake
Livingston Dam has been declared stable by a dam
inspector from the Texas Commission on Environmental
Quality.
Built, owned and operated by the
Trinity River Authority of Texas (TRA), Lake
Livingston is the largest lake constructed solely
for water supply purposes located totally within the
State of Texas. The lake covers approximately 83,000
surface acres, with a normal pool elevation of 131
feet above mean sea level. The Livingston Dam,
constructed across the Trinity River approximately
seven miles southwest of the city of Livingston, is
2½ miles in length and has an average height of 55
feet.
