FORT WORTH, Texas – The U.S. Army Corps of Engineers representatives at Canyon Lake announced today it will initiate release control from the Guadalupe-Blanco River Authority due to significant rainfall and runoff in the upper Guadalupe River Basin near Comfort, Texas.
A peak flow of nearly 84,000 cubic feet per second (CFS) was measured at this gauge around 3:45 a.m. and flows exceeding 70,000 cubic feet per second were measured over a four hour period. The Fort Worth District Reservoir Control Office forecasts the lake could rise as high as 918.5 to 919 feet above mean sea level by noon Tuesday.
This nine and one half to 10-feet rise into the flood pool requires coordination between USACE and GBRA to switch over releases from GBRA to USACE tomorrow afternoon starting at 4 p.m. Then around 7 p.m. the Corps will make further incremental flood release increases to achieve a flow of 2,500 cubic feet per second by midnight.
On Tuesday morning around 4 a.m., USACE will continue to increases flood releases from 2,500 to approximately 5,000 cubic feet per second. These near 5,000 cubic feet per second releases will be maintained until the pool drops to 911 feet. At this elevation, inflows will be reassessed and the Corps will consider possible flood release changes.
For additional information please contact the Canyon Lake office at 830-964-3341.
