Fish populations in Canyon Reservoir were surveyed in 2011 using electrofishing and in 2012 using gill nets. This report summarizes results of the surveys and contains a fisheries management plan for the reservoir based on those findings.

Reservoir Description

Canyon Reservoir is an 8,308-acre impoundment of the Guadalupe River located in Comal County. It was constructed in 1964 by the U.S. Army Corp of Engineers (USACE) for purposes of flood control, water conservation and recreation. Canyon Reservoir has a drainage area of approximately 1,452 square miles and a shoreline length of 90.5 miles. The reservoir lies within the Edwards Plateau ecological area.

Management History

Important sport fish include largemouth bass, striped bass, white bass and catfish species. Striped bass were introduced in 1973 and stocked until 1983, then restocked at a lower rate (5/acre) in 1989. White bass were managed under an experimental 12-inch minimum length limit. The regulation was rescinded in 2004 after analysis indicated environmental factors, not angler harvest, were probably more influential in determining white bass population density. Largemouth bass were present in the reservoir and have been managed under statewide regulations. Blue catfish were introduced in 1991 to provide enhanced catfish opportunities for anglers. The management plans from the 2007 survey report included maintaining fish attractor sites; continued annual stockings of striped bass; and increasing or enhancing pier fishing opportunities.

Fish Community

Management Strategies

Annual striped bass stockings should continue to be requested at the present stocking rate of 5/acre. Fish attractor sites should continue to be replenished with brush as needed.
