This is the authors' summary from a 20-page report. For a copy of the complete report, use the download link in the sidebar.

Fish populations in San Augustine City Lake were surveyed in 2010 using electrofishing and trap netting and in 2011 using gill netting. A vegetation and access survey was conducted in 2010. 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 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- to 18-inch slot-length limit. The slot-length limit was implemented in 2004. Based on 2010 electrofishing results, the slot-length limit has not had any detectable affect on increasing the numbers of 14- to 18-inch largemouth bass. Sportfish body condition was adequate but prey fish abundance was less than desired. 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, coverage steadily declined, and no hydrilla has been observed since 2007.
