Fish populations in Highlands Reservoir were surveyed in 2015 using electrofishing and trap netting and in 2016 using gill netting. This report summarizes the results of the surveys and contains a management plan for the reservoir based on those findings.

Reservoir Description

Highlands Reservoir is a 1,437-acre impoundment and canal system located on Goose Creek in the San Jacinto River Basin. The reservoir is located approximately 1 mile upstream from McNair, Texas and two miles north of Interstate Highway 10 in east central Harris County. The reservoir is owned by the San Jacinto River Authority and has a normal capacity of about 3,800 acre-feet. The twelve-foot-high Highlands Reservoir Dam has a crest length of 37,000 feet; it was constructed by the Federal Works Agency in 1943. The reservoir is used for local water supply. Highlands Reservoir has moderate productivity. Habitat features consist of standing timber, riprap, and non-native vegetation.

Management History

Highlands Reservoir was opened to the public in 2015; therefore, no previous fisheries data had been collected. Previous management strategies were solely for water supply.

Management Strategies

The primary goal is to continue to characterize the reservoir’s habitat and fish populations through surveys and to improve the fishery by continuing to stock Florida Largemouth Bass when hatchery production allows. Efforts will be made to inform the public about the negative impacts of aquatic invasive species. Standard monitoring surveys (trap net, gill net, electrofishing, habitat, and access) will be conducted again in 2019-2020 with additional vegetation surveys being conducted in 2016-2017, 2017-2018, and 2018-2019.
