CASSIN LAKE. Cassin Lake is in the San Antonio River basin on Minita Creek two miles west of Southton in southeastern Bexar County (at 29°18' N, 98°27' W). The artificial lake was built in 1907 for irrigation purposes and was evidently named for William Cassin, an early landowner for whom the town of Cassin was also named. In the early 1990s the lake, which has a maximum capacity of 580 acre-feet, was owned and operated by Medina Properties Limited. The surrounding terrain is flat to gently rolling and is surfaced by clay loam that supports mesquite, cacti, and grasses.
