Fish populations in Alan Henry Reservoir were surveyed in 2013 using electrofishing and trap netting and in 2014 using gill netting. Historical data are presented with the 2013-2014 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. The reservoir is owned by the City of Lubbock, Lubbock County, Texas and is currently used for recreational purposes and as a water supply. Alan Henry Reservoir first filled to capacity in October 2004, and the water level remained within 5 feet of conservation pool until 2011 when it began a steady decline to approximately 14 feet below conservation pool at sampling in 2013 and 2014. Productivity of Alan Henry Reservoir was characterized as low. Habitat features consisted of flooded terrestrial vegetation, rocks, and very small amounts of native submerged aquatic plants.

Management History

Sport fish in the reservoir included Blue Catfish, Channel Catfish, Flathead Catfish, Alabama Bass, Largemouth Bass, and White Crappie. Alabama Bass were managed with restrictive harvest regulations since their introduction in 1996 until September 1, 2011 in order to establish a viable 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 25 entries into the ShareLunker program since 2000.
