Fish populations in Buchanan Reservoir were surveyed in 2015 using electrofishing and in 2016 using gill netting. This report summarizes the results of the surveys and contains a fisheries management plan for the reservoir based on those findings.

Reservoir Description

Buchanan Reservoir is a 22,211-acre impoundment of the Colorado River located in Burnet and Llano counties. It was constructed in 1937 by the Lower Colorado River Authority (LCRA) for purposes of hydroelectric power, water supply, flood control, and recreation. The reservoir lies within the Edwards Plateau ecological area. Its drainage area is approximately 31,250 square miles. Shoreline length is approximately 140.6 miles. Only small amounts (<1 acre) of aquatic vegetation have ever been documented in the reservoir.

Management History

Important sport fish include White Bass, Striped Bass, Sunshine Bass, Largemouth Bass, and catfish species. The management plan for 2011 included continuing annual stockings of Striped Bass, monitoring the Striped Bass population with additional gill netting, and permitting the stocking of Sunshine Bass by the Lake Buchanan Reservoir Conservation Corporation (LBCC). Striped Bass have been stocked almost annually since 1977, and the reservoir is regarded as one of the best Striped Bass fisheries in Texas. Sunshine Bass have been stocked annually since 2006 by the LBCC. The Florida subspecies of Largemouth Bass was stocked in the reservoir in the late 1970’s and once again in 2008 and 2015 to increase Florida Largemouth Bass genetic influence in the population. Blue Catfish were stocked in 1989 and 1990 to help establish a naturally-reproducing population. White Bass were managed under an experimental 12-inch minimum length limit from 1995 to 2003. The regulation was rescinded after analysis indicated environmental factors, not angler harvest, were probably more influential in determining White Bass population density.
