Lake Lawtonka is a medium-sized reservoir located in southwest Oklahoma, just north of Medicine Park and 15 miles northwest of Lawton in Comanche County. As the oldest reservoir in Oklahoma, constructed in 1905, it serves as the primary water supply for Lawton and Fort Sill. The lake encompasses 2,398 surface acres with 21 miles of shoreline and is framed by the scenic Wichita Mountains to the west with Mount Scott providing a striking backdrop. Lawtonka has a maximum depth of 60 feet near the dam with an average depth of 23 feet at full pool. The reservoir was formed by a dam 60 feet high and 375 feet long across Medicine Bluff Creek. With relatively clear water compared to other Oklahoma reservoirs, Lake Lawtonka has developed a reputation as one of the best fishing destinations in southwestern Oklahoma, particularly for smallmouth bass, having produced Oklahoma's state record smallmouth bass weighing 8.5 pounds.
