Description: This information identifies and delineates the boundaries of stream reaches containing federal and state threatened or endangered aquatic species. The species included in this analysis were limited to species inhabiting primarily lotic, or riverine, habitats including fish, mollusks, crayfish, snails and the wood turtle (Clemmys insculpta). Aquatic resource professionals from the Virginia Department of Game and Inland Fisheries reviewed several data sources in the development of this spatial information. The spatial data used for development include DGIF's T&E Species Observations (DGIF 2016) a hydrography data layer (USGS, NHD 1:24,000K), a county boundary data layer (DCR, 2016), and a roads data layer (VDOT 2007). Additional data sources included regional scientific literature and professional resource experience. The reaches were delineated based on the presence of a threatened or endangered species and extended to include suitable habitat if known. Stream reaches are defined as confluence to confluence and boundaries were extended to road crossings or county boundaries to facilitate text descriptions and recreation of the boundaries. No specific upstream protection zones were added.
