Fish populations in Lake Timpson were surveyed in 2012 using electrofishing and trap netting and in 2013 using gill netting. Historical data are presented with the 2012-2013 data for comparison. This report summarizes the results of the surveys and contains a management plan for the reservoir based on those findings.

Reservoir Description

Lake Timpson is located in Shelby County. The Shelby County Freshwater Supply District is the controlling authority. Primary uses are water supply and recreation. This reservoir has a surface area of 223 acres, a shoreline length of 8 miles, and an average depth of 8 feet. Water level fluctuations average 1-3 feet annually. Boat and bank access is adequate, with one boat ramp present.

Management History

Important sport fish included Largemouth Bass, crappie, and catfish. Prior to 1994, Largemouth Bass were managed under statewide regulations. In 1994, Largemouth Bass regulations were changed to a 14- to 21-inch slot length limit. This regulation has had the desired effect of producing increased numbers of Largemouth Bass that are within the protective slot length limit. In 2003, hydrilla was found in Lake Timpson, and coverage expanded to 40% of the reservoir surface area in 2004. Triploid Grass Carp were stocked in 2004 at a rate of 5 fish/vegetated acre (448 fish) to reduce hydrilla coverage. Since 2006, no hydrilla has been observed. In 2010, giant salvinia was discovered, and eradication was accomplished with numerous herbicide treatments; no plants were observed in 2011 or 2012.
