Fish populations in Granbury Reservoir were surveyed in 2005 using electrofishing and trap nets and in 2006 using gill nets. 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, Hood County, Texas. Constant water level is maintained by an open spillway and retention time has been estimated at 260 days. Granbury Reservoir has been hampered by golden alga since 2001. Habitat features mainly consisted of boat docks, extensive bulk heading, standing timber, and dead trees and stumps.

Management History

Important sport fish include largemouth bass and striped bass. Both have been affected by annual, toxic golden alga blooms since 2001. Prior to this, largemouth bass were being regulated with a more restrictive 16-inch minimum length limit, five fish daily bag, which is still in place today. Stripers have been regulated with statewide regulations, and although more restrictive limits were considered in 2002, the desire to maintain consistent regulations for user groups on Granbury and Whitney Reservoirs out-weighed expected benefits at the time. Other species of fish have withstood significant mortalities over the past five years; fortunately the prey base has rebounded nicely year after year. Recent efforts to mitigate the loss of sport fish due to golden alga have included annual striped bass stockings since 2001 and Florida largemouth bass stockings in 2003 and 2004.
