Lake Mexia Is Fishing Water and a Working Water Supply

Lake Mexia lies on the Navasota River about seven miles southwest of Mexia. Bistone Dam was completed in June 1961, and deliberate impoundment began the same day. At conservation pool, the lake covers 1,009 acres and holds a normal capacity of 4,687 acre-feet.

The Bistone Municipal Water Supply District owns and operates the reservoir. Its purposes include municipal and industrial water supply as well as recreation. The lake is part of the area's working infrastructure as well as a fishing stop.

The lake has a maximum depth of 20 feet, and normal clarity is murky to turbid. Docks, piers, and shallow aquatic plants provide cover. Largemouth bass, white bass, crappie, channel catfish, and blue catfish make up the main fishing profile.

Public access is narrow and specific. TPWD lists one boat ramp off US 84, seven miles west of Mexia. As checked July 31, 2026, the ramp was open all year with no fee and was operated by the Bistone district.

Lake Mexia's two jobs sit on the same stretch of water. The Navasota reservoir holds water for nearby communities and industry while its docks, plants, and public ramp support a smaller fishing landscape.
