USACE Reduces Release to 2,000 cfs
Flows to Guadalupe River will drop dramatically later this week.
The U.S. Army Corps of Engineers (USACE) reduced water releases to approximately 2,000 cubic feet per second (cfs) on Monday due to Canyon Lake’s declining elevation, Guadalupe-Blanco River Authority (GBRA) announced on its website.
Due to elevated inflows still coming into Canyon, USACE will continue to make flood releases until the reservoir elevations drops to 910 msl. Once the inflows have subsided and with the lake elevation lower, USACE will enable GBRA to release the remaining flood pool utilizing the Canyon Hydroelectric Generating Plant.
When GBRA begins making releases, the flow downstream of Canyon Dam will be approximately 800 cfs or lower depending on inflows to reservoir measured at Spring Branch.
As USACE announces the timing, duration, and flow rate of releases from Canyon Dam, GBRA said it will forward the information.
USACE last week decided to maintain water releases at approximately 3100 cubic feet per second (cfs) at Canyon Reservoir in response to recent heavy rains.
Releases from Canyon Dam are based on current inflows and rainfall. Property owners, recreationalists and other stakeholders should take notice of the changing downstream river flows.
