This is the authors' summary from a 29-page report. For a copy of the complete report, use the download link in the sidebar.

Fish Populations in Granbury Reservoir were surveyed in 2013 with electrofishing. Low water levels prevented trap netting surveys in winter 2013 and gill netting surveys in 2014. This report summarizes the results of the surveys and contains a management plan for the reservoir based on those findings.

Reservoir Description

Granbury Reservoir is an 8,700-acre impoundment located within the Brazos River system in Hood County, Texas. Near constant water level is maintained by a spillway consisting of 16 tainter gates and 2 sluice gates; retention time has been estimated at 260 days. Primary water uses include storage of flood and storm waters, municipal water supply, power plant cooling, and recreation. Granbury Reservoir has only moderate productivity, yet the fishery has been hampered by golden algae since 2001. Habitat features were dominated by extensive bulk heading, natural shoreline and docks/piers.

Management History

Sport fishes in Granbury Reservoir are currently managed with statewide regulations with the exception of a 16-inch minimum length limit on Largemouth Bass. Important sport fish include Largemouth Bass and Striped Bass. Both have been affected by nearly annual, toxic Golden Algal blooms since 2001. Efforts to mitigate these losses included collecting supplemental fisheries data, stocking Striped Bass annually, and stocking Florida Largemouth Bass. Trap netting became optional in 2009, and because of weak crappie catch rates in prior years, it is no longer a primary objective of scheduled sampling. Most recently, a public relations campaign began within the district to inform and educate constituents about zebra mussels in order to prevent their introduction into Granbury Reservoir. Recent low water levels have made monitoring difficult.
