About Medina Lake
Medina Lake northwest of San Antonio is an irrigation reservoir owned by the Bexar-Medina-Atascosa Counties Water Control and Improvement District, not the Corps, which is why it has no flood pool and can drop to a small fraction of full during drought. Conservation pool is 1,064.2 ft; the level here comes from the Texas Water Development Board's daily gauge report.
