Description: These are mussel streams and rivers updated in July 2024 and based on National Hydrography Dataset Plus High Resolution (NHDPlus HR) stream segments. Mussel attributes include StreamGroup and Description:Group 1: High Quality Streams (as listed by the WVDNR and having potential habitat for mussels) and state mussel streams. Endangered species not expected.Group 2: Small to mid-sized streams with endangered species expected.Group 2: Critical Habitat: Small to mid-sized streams with US Fish and Wildlife Service designated critical habitat.Group 2.5: Typically small streams that join either a Group 2 or Group 4 stream that may potentially contain endangered species; thus the lower half mile of the stream is considered a Group 2.Group 2P: Small to mid-sized streams with species proposed for listing by US Fish and Wildlife Service.Group 3: Large rivers where endangered species are not expected. These include the Ohio River upstream of Hannibal Lock and Dam and the Monongahela River.Group 4: Large rivers where endangered species are expected. These include the Ohio River downstream of Hannibal Lock and Dam, Little Kanawha River (slack-water section adjoining the Ohio River), and the Kanawha River.Group 4: Critical Habitat: Small to mid-sized streams with US Fish and Wildlife Service designated critical habitat.These data are based on the National Hydrography Dataset Plus High Resolution (NHDPlus HR) dataset. NHDPlus HR is a scalable geospatial hydrography framework built from the High Resolution (1:24,000-scale or better) National Hydrography Dataset.
