Expanded Local Carrizo

Medina Lake

Through an agreement with the Bexar-Medina-Atascosa Water Control & Improvement District No. 1, the Medina project was established as San Antonio's first modern surface water project in 2000. With access to 19,974 acre-feet* An acre-foot of water is equivalent to 325,851 gallons. per year, water stored in Medina Lake is delivered to SAWS' ultra-filtration membrane plant located on the Medina River in southwest Bexar County.

Presently, the facility has treatment capacity of up to 13,000 acre-feet per year, although this water supply hasn't been utilized since 2013.

In Times of Drought

However during extreme droughts, Medina Lake's small contributing watershed and location over the Edwards Aquifer Recharge Zone mean that SAWS considers it to have zero firm yield. This is consistent with the South-Central Texas Regional Water Planning Group and the Texas Water Development Board State Water Plan.
