Reservoir Description

Sheldon Reservoir is a 1,229-acre reservoir in Sheldon Lake State Park on Culpepper Bayou in Harris County, Texas. The reservoir has a drainage area of 4 square miles and a shoreline length of 13.1 miles. The reservoir has a mean depth of 3 feet and a maximum depth of 20 feet. Sheldon Reservoir is a highly productive wetland ecosystem that hosts a diverse community of fish and wildlife species that attract anglers, boaters, and wildlife viewers from across the state.

Management History

Sheldon Reservoir is a very important asset to Texas Parks and Wildlife and to the people of Houston. To make the most of this resource, Inland Fisheries Division has worked closely with Sheldon Lake State Park’s and Infrastructure’s staffs to improve the reservoir in conjunction with the development of the Sheldon Environmental Learning Center. Heavy infestations of hydrilla, giant salvinia, and water hyacinth have greatly impeded recreational use at Sheldon Reservoir. However, herbicide treatments in 2011, 2012, 2014, and 2015 have improved the situation.

Management Strategies

The primary challenge at Sheldon Reservoir is aquatic vegetation management and water level management. An integrated pest management strategy has been implemented to address the aquatic vegetation problem. Sheldon Lake State Park staff continue to explore ways to supplement water supply to Sheldon Reservoir in low rainfall years. Electrofishing and angler access surveys will be conducted every four years. Aquatic Nuisance Species surveys will be conducted annually, and efforts to inform the public about the negative impacts of aquatic invasive species and preventive measures will continue.
