Fish populations in San Augustine City Lake were surveyed in 2006 using electrofishing and trap nets and in 2007 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

San Augustine City Lake is an impoundment of Carrizo and Caney creeks. The City of San Augustine is the reservoir’s controlling authority. Primary uses are water supply and recreation. This reservoir has a surface area of 200 acres, a shoreline length of 5.5 miles, and a mean depth of 10 feet. Water level fluctuations are estimated to average 3-feet annually. Boat and bank access is adequate, with one boat ramp present.

Management History

Important sport fish include largemouth bass, white and black crappie, and catfish. The management plan from the 2002 survey report included changing the 18-inch minimum length limit for largemouth bass to a 14-18 inch slot length limit. The slot length limit was implemented in 2004. Based on electrofishing results from the fall of 2006 it does not yet appear that the slot length limit has had the desired effect of producing increased numbers of quality-size largemouth bass. Growth rates of largemouth bass appeared to improve since March 2003; however body condition was less than adequate despite a plentiful forage base. Hydrilla has been problematic over the years, covering approximately 75% of the reservoir surface area in 2002. From 2002-2003, triploid grass carp were stocked at a rate of 4/vegetated acre (600 fish total) in an attempt to reduce hydrilla coverage to 10-15%. Since these stockings hydrilla coverage has steadily declined with 16% coverage observed during the summer of 2006.
