Fish populations in Sulphur Springs Reservoir were surveyed in 2005 using electrofishing and trap nets, and in 2006 using gill nets. Aquatic vegetation and habitat surveys were conducted during August 2005. This report summarizes the results of the surveys and contains a management plan for the reservoir based on those findings.
Sulphur Springs Reservoir is a 1,766-acre impoundment located in Hopkins County, Texas, on White Oak Creek, a tributary of the Sulphur River. It was constructed by the City of Sulphur Springs in 1973 as a municipal water supply. Habitat consists primarily of featureless mud banks with very little structural cover. Water clarity in the reservoir is extremely low due to high levels of suspended solids in the water column.
Important sport fish include largemouth bass, white crappie, and blue catfish. The management plan from the 2001 survey report included investigating options to reduce turbidity and improve fisheries resources. Fisheries utilization is limited; however, passive-gear and active-gear catfish fisheries are present in the reservoir.
- Prey species: Predominant prey species in the reservoir include gizzard shad and bluegill. Electrofishing catch of gizzard shad was moderate, with the majority being available as prey to most sport fish. Electrofishing catch of bluegills was low and no bluegills were over 6-inches long. Threadfin shad historically provided additional forage for sport fish in the reservoir, but none were collected during 2001 or 2005.
- Catfishes: Gill net catch rate of blue catfish was relatively low, but most fish were of legal size. Although channel catfish were caught in previous surveys of the reservoir (Myers and Storey 2002), no channel catfish were caught in 2006.
- Largemouth bass: No largemouth bass were sampled during 2005 or 2001. This indicates that largemouth bass were either extremely rare or the high lake turbidity makes it difficult to observe fish during electrofishing sampling.
- White crappie: White crappie were present in the reservoir, and the population was dominated by small fish. No legal-sized white crappie were sampled in 2005.
Conduct standard monitoring with trap nets, gill nets, and electrofishing surveys in 2009-2010. Conduct aquatic vegetation and habitat surveys in 2009.
