Fish populations in Casa Blanca Reservoir were surveyed using electrofishing and trap nets in 2004 and 2006, and gill nets in 2003, 2005, and 2007. This report summarizes the results of the surveys and contains a management plan for the reservoir based on those findings.

Reservoir Description

Casa Blanca is a 1,680-acre reservoir located near Laredo, Texas, in the Rio Grande River watershed. The reservoir and associated Lake Casa Blanca State Park have been managed by Texas Parks and Wildlife Department since 1990. Water level records are not kept for this reservoir. Maximum water level fluctuation during the study period was observed to be about 2 feet and water level was sufficient proving adequate angler and boat access. Handicap specific facilities were not present. At the time of sampling, the habitat was primarily rocky shoreline, flooded terrestrial vegetation and native emergent vegetation.

Management History

Important sport fishes include largemouth bass, catfishes, white crappie, and palmetto bass. Harvest of all sport fish species except largemouth bass has been regulated according to statewide size and daily bag limits. Largemouth bass harvest is currently regulated with an 18-inch minimum size limit and a 5-fish daily bag limit. Palmetto bass have been stocked regularly with stockings occurring in four years since 2000. Florida largemouth bass fingerlings were last stocked in 2004.
