SAN ANTONIO (AP) -- Medina Lake's dam gates have been shut in an effort to delay the reservoir from going dry.
The San Antonio Express-News reports the lake level is at about 13 percent capacity and because of evaporation and seepage will likely keep falling as the drought persists. The gates were closed last week.
Closing the dam gates shouldn't drastically affect the flow of the Medina River downstream, which officials say isn't directly fed by releases from the dam but by springs and water migrating through porous limestone in the lakebed.
Ed Berger, manager of the Bexar-Medina-Atascosa Water Control and Improvement District No. 1, which owns and operates Medina Dam, says two gates release water into Diversion Lake, a smaller reservoir below Medina Lake which feeds the irrigation district's canal system.
