Fish populations in Lake Dunlap were surveyed in 2017 using electrofishing and trap netting and in 2018 using gill netting and additional trap netting. Historical data are presented with the 2017-2018 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 Dunlap is a 410-acre impoundment located in New Braunfels, Texas and is part of the Guadalupe River chain lakes. Lake Dunlap is classified as a mainstream reservoir and has a fairly constant water level. Substrate in the upper section is composed primarily of rock and gravel, while the middle and lower sections of the reservoir are composed of clay, sand, and silt. Habitat features included boat docks, rocks, flooded timber, and several native vegetation species.

Management History

Important sport fish include Channel and Flathead Catfishes, Largemouth Bass, and crappie species. The management plan from the 2013 survey report focused on refining trap net sampling for crappies, monitoring and management of invasive vegetation, supplement losses of fisheries habitat with a native vegetation planting, and publicizing the Largemouth Bass and catfish populations.
