Medina Lake is a reservoir on the Medina River in the Texas Hill Country of the United States. It is operated by the Bexar/Medina/Atascosa County Agricultural District. Medina Dam was completed in 1913 in a privately financed project, creating the lake to supply irrigation water for local agricultural use. Lake Medina is in northeastern Medina County and southeastern Bandera County, about 40 miles (64 km) northwest of San Antonio.
It is a crescent-shaped reservoir running west to east. It is 18 miles (29 km) long and 3 miles (5 km) wide at its broadest point. It is contained by the Medina Dam at the lake's south end. At the time of the dam's construction, it was the largest concrete dam in the country and the fourth largest dam overall. The dam is listed on the National Register of Historic Places.
The lake is fed by and discharges back into the Medina River, and serves both recreational and irrigation uses. Communities located along the lake are Mico, Lake Medina Shores and Lakehills.
