High Flows Continue On Hydro Lakes

SEGUIN, TEXAS – Recent heavy rainfall in the Guadalupe River Basin, particularly in the area above and around Canyon Reservoir, has prompted the U.S. Army Corps of Engineers (USACE) to make releases that will vacate the flood pool at Canyon.

Canyon’s elevation reached a high of just above 920 mean sea levels (msl) and was at 919.30 msl as of Tuesday afternoon. The USACE is releasing 4,790 cubic feet per second (cfs) as indicated by the gauge at Sattler, Texas.

Because of the need to release those flood flows, it has created a situation where flows of about 6,000 cfs are occurring at Meadow Lake (also known as Lake Nolte). Guadalupe-Blanco River Authority (GBRA) officials are indicating the high flows at Meadow Lake will continue through approximately June 25, assuming no additional rainfall. As a result, the floodgates at Meadow Lake also will remain in the current position through June 25.

With high flows passing through the hydroelectric lake system, GBRA officials urge lake users to exercise caution on the hydro lakes.

The GBRA was established by the Texas Legislature in 1933 as a water conservation and reclamation district. GBRA provides stewardship for the water resources in its 10-county statutory district, which begins near the headwaters of the Guadalupe and Blanco rivers, ends at San Antonio Bay, and includes Kendall, Comal, Hays, Caldwell, Guadalupe, Gonzales, DeWitt, Victoria, Calhoun, and Refugio counties.
