The hydro lakes owned and operated by the Guadalupe-Blanco River Authority impound water needed to generate electricity. They are also popular residential and recreation areas.
All lakes are constant level unless lowered for dam or spillgate maintenance.
The six hydro lakes were created in the late 1920's and early 1930's when the Texas Hydro-Electric Corporation and the Texas Power Corporation built six dams and powerhouses to produce hydroelectricity using the natural flows of the Guadalupe River. GBRA acquired these facilities in the 1960's and operates them as part of its Guadalupe Valley Hydroelectric Division. The powerhouses are monitored and controlled from a central control room at the GBRA offices in Seguin. Most of the shoreline is private property with numerous bulkheads and boat docks.
