The Lake Houston watershed is located northwest of Jackson Bayou watershed and north of the Lower San Jacinto River watershed. The East and West Forks of the San Jacinto River and the San Jacinto River are the primary streams that flow through the watershed before the San Jacinto River flows into the Lower San Jacinto River watershed.
Lake Houston is a 12,240-acre reservoir constructed on the San Jacinto River. It has a drainage area of approximately 2,600 square miles. This watershed has sedimentation issues that the Texas Parks and Wildlife (TPWD), the City of Houston, the San Jacinto River Authority (SJRA), Texas A&M University, the U.S. Army Corps of Engineers are trying to address in a cooperative project.
Lake Houston also has invasive species problems that impede access and reduce recreational activity. The San Jacinto river was named one of the ten most endangered rivers in 2006 due to habitat damage caused by development. Fisheries for crappie, Lake Houston Aerial catfish, and largemouth bass are species that will benefit from this habitat improvement partnership.
