Although the primary purpose of Smith Mountain Lake is power generation, SML is an outstanding fishery which supports black bass (largemouth and smallmouth), hybrid striped bass (Stripers), sunfish, crappie, white and yellow perch, channel catfish, flathead catfish, white catfish, carp, and Asian grass carp.
The Virginia Department of Wildlife Resources (VA DWR) fishery biologists, stationed in Forest, Virginia, monitor and manage the SML fishery. Smith Mountain Lake Association (SMLA) Habitat, Submerged Aquatic Vegetation (SAV), and Invasive Species volunteers assist VA DWR in monitoring these three fishery health interrelated areas.
Native SAV has been present in SML since formation in 1966. Hydrilla and other invasive weeds began growing out of control and degraded the recreational experience on the lake for many users, especially in small coves. Sterile Asian grass carp were introduced approximately ten years ago to feed upon and remove the Hydrilla, but unintentionally, they also depleted SML of most SAV. This lack of SAV created a problem for the bass fishery because SAV provides protection for fry (juvenile fish) enabling them to reach a size and maturity enough to sustain their population levels.
VA DWR fishery biologist, Dan Wilson, with the help of APCO funding, searched for a way to provide juvenile fish habitat and started with underwater rock piles, wood pallets, and some wood pyramid structures. These all helped.
Since 2017, VA DWR has been modifying and deploying PVC fish habitat structures that have significantly increased the survival rates of the fry. These habitats have been deployed in approximately eight to ten feet of water at 217 locations throughout the lake as of 2023. Deployment locations are tracked by GPS latitude/longitude and are available to the public from VA DWR and SMLA.
