Fish populations in Stillhouse Hollow Reservoir were surveyed in 2009 with a boat electrofisher and in 2010 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

Stillhouse Hollow Reservoir is a 6,430 acre reservoir located in Bell County, Texas. The impoundment was created in 1968 and is operated by the United States Army Corps of Engineers. Primary water uses include municipal water supply and recreation. Water levels fluctuate about 5 feet annually; however elevations were near conservation pool (i.e., 622) during sampling periods. Habitat features mainly consisted of natural shorelines.

Management History

Sport fishes in Stillhouse Hollow Reservoir have always been managed with statewide regulations. Important sport fish include largemouth and smallmouth bass. The management plan from the 2002 survey report included annual evaluations of hydrilla coverage, and annual comparisons of smallmouth bass catch rates between standardized and non-standardized stations. Standard electrofishing surveys were conducted in 2002 and 2003; however district priorities changed in 2004 and these annual surveys were dropped from the four year rotation. A tier IV age and growth sample was conducted on largemouth bass in 2005 as a result of the district reprioritization. Annual electrofishing of subjectively chosen stations began in 2002, but after only one survey, it was found that the numbers of smallmouth bass collected were insufficient for analysis, and these surveys were dropped. Hydrilla coverage is still surveyed on an annual basis.
