This is the authors' summary from a 39-page report. For a copy of the complete report, use the download link in the sidebar.

Fish populations in Alan Henry Reservoir were surveyed in 2017 using electrofishing and in 2018 using gill netting. Anglers were surveyed from March 2015 through May 2015 and April 2018 through June 2018 with creel surveys. Historical data are presented with the 2015-2018 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

Alan Henry Reservoir was constructed in 1993 on the South Fork of the Double Mountain Fork of the Brazos River. It is located 6 miles east of Justiceburg in Garza County, Texas. At conservation pool (2,220 feet above mean sea level; FMSL), Alan Henry Reservoir is a 2,884-acre impoundment. Productivity of Alan Henry Reservoir is characterized as low. Habitat features consist of flooded terrestrial vegetation, rocks, and very small amounts of native submerged aquatic plants.

Management History

Sport fish in the reservoir includes Blue Catfish, Channel Catfish, Flathead Catfish, Alabama Bass, Largemouth Bass, and White Crappie. Alabama Bass were managed with an 18-inch minimum length limit since their introduction in 1996 until September 1, 2011 in order to establish a self-sustaining population. Largemouth Bass harvest regulations were liberalized with the allowance of 2 fish under the 18-inch minimum length limit in 2002 to promote recruitment of fish into size classes larger than the 18 inch minimum length limit. Alan Henry Reservoir has produced 27 entries into the ShareLunker program since 2000.
