About Medina Lake
Medina Lake sits on the Medina River in Medina and Bandera counties, northwest of San Antonio. It is one of the oldest large reservoirs in Texas: construction began in November 1911 and the lake started filling on May 7, 1913. At the time it was the largest dam in Texas and the fourth largest in the United States. The lake was built for irrigation and is owned and operated by the Bexar-Medina-Atascosa Counties water district, which sends water to farms through a diversion dam about four miles downstream. Full conservation pool is 1,064.2 ft.
Why Medina Lake's level swings so much
Medina Lake depends on Hill Country rain to refill, so long dry spells hit it hard. In the Texas Water Development Board record, which starts in 1997, it was 100% full in August 1997, but it has spent most of the last decade far below that. It dropped under 10% full in 2012 to 2015 and again from 2022, and reached a low of 968.74 ft (1.9% full) on May 26, 2025.

Where this data comes from
The water level is published by the Texas Water Development Board (station Medina) and refreshed on this page every day. Full pool comes from Texas Water Development Board; the normal range is calculated from official daily readings for 2006-2025. Recent readings are provisional and may be revised. See data sources & methodology.
The lake is owned by an irrigation district, so the state readings from the Texas Water Development Board are the main public record of its level.
