Project Area

River Basin: San Jacinto

Water Body: East Fork San Jacinto (1003), Winters Bayou (1003A), Nebletts Creek (1003B), and Boswell Creek (1003C)

Location: Cities of Houston, Splendora, Roman Forest, Huntsville, North Cleveland, Cleveland, and Plum Grove

Background

The East Fork San Jacinto watershed in Harris, Walker, Montgomery, Liberty, and San Jacinto counties includes 410.5 square miles of mixed land uses—from small urban centers to natural landscapes—within the Sam Houston National Forest. The East Fork of the San Jacinto River (East Fork) is part of the larger San Jacinto River Basin above Lake Houston, a vital source of drinking water, recreation, and wildlife habitat for the Houston region.

Boswell Creek did not meet state water quality standards for primary contact recreation due to high levels of fecal bacteria. Winters Bayou was listed in the 2020 Texas Integrated Report of Surface Water Quality because of a concern for high bacteria levels. Increasing urban development in the watershed is expected to exacerbate nonpoint source pollution and water quality issues.
