This is the authors' summary from a 55-page report. For a copy of the complete report, use the download link in the sidebar.

Fish populations in Possum Kingdom Reservoir were surveyed in 2020 and 2022 using electrofishing and 2022 using trap netting and gill netting in 2021 and 2023. Anglers were surveyed from September 2020 through May 2021 with a creel survey. Historical data are presented with the 2020-2023 data for comparison. This report summarizes the results of the surveys and contains a management plan for the reservoir based on those findings.

Reservoir Description

Possum Kingdom Reservoir is a 15,588-acre impoundment located on the Brazos River approximately 76 miles west of Fort Worth. It has a primarily rocky shoreline with many boat docks. The reservoir was within two feet of conservation pool from January 2019 to January 2022 and then receded to seven feet below conservation pool around January 2023. Possum Kingdom has had a history of golden alga caused fish kills since the early 2000’s, though recent events have been rather isolated in scope.

Management History

Important sport fish populations include catfish spp., White Bass, Striped Bass, and Largemouth Bass. Possum Kingdom was managed under statewide regulations until September 1, 2002, when the Largemouth Bass minimum length limit was raised to 16 inches and the Striped Bass bag limit was lowered to two per day in response to a golden alga (Prymnesium parvum) fish kill that occurred in early 2001. The Striped Bass bag limit was returned to the statewide bag limit on September 1, 2012. The Largemouth Bass length limit returned to the statewide 14-inch minimum on September 1, 2018. The statewide combined Channel and Blue Catfish regulation changed September 1, 2021, from a 25 fish bag limit with a 12-inch minimum length limit to a 25 fish bag limit (in any combination, only 10 fish 20-inch or greater in length), no length limit. Major golden alga mortality events have occurred in 2001, 2003, 2007, and 2010. Smallmouth Bass were stocked in 2020, 2021 and 2022 to rebuild the population. Artificial habitat has been placed around the reservoir since 2013.
