This is the authors' summary from a 34-page report. For a copy of the complete report, use the download link in the sidebar.

Buchanan Reservoir was surveyed in 2003 using trap netting and electrofishing, and in 2004 using gill netting. Structural habitat and angler access surveys were conducted in 2004. Caution should be used when comparing 2004 gill netting catch rates with previous years because sampling location strategies were altered following the white bass length limit evaluation in 2003. This report summarizes the results of these surveys and contains a fisheries management plan for the reservoir based on those findings.

Reservoir Description

Buchanan Reservoir is a 23,060 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 of which 11,900 square miles are probably non-contributing. Shoreline length is approximately 140.6 miles.

Management Strategies

Based on current information, the reservoir should continue to be managed with existing regulations. The white bass 12-inch regulation evaluation was completed in 2002, and the length limit decreased to 10 inches. Striped bass angling at this reservoir is popular enough to support several full-time fishing guides. Gill netting surveys should continue to be conducted every two years to monitor population characteristics of these fisheries. Annual stockings of striped bass should be continued, but at a reduced rate of 5 fingerlings per acre.
