Geometry Type: esriGeometryPolyline

Description: These are mussel streams and rivers updated in February 2018 and based on National Hydrography Dataset (NHD) 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 listed mussel streams. Endangered species not expected.Group 2: Small to mid-sized streams with endangered species expected.Group 2.5: These are typically small streams that join either a Group 2 or Group 4 stream which may potentially contain endangered species and thus the lower half mile of the stream is considered a Group 2.Group 3: Large Rivers where endangered species are not expected. These include the Ohio River upstream (US) of Hannibal Lock and Dam and the Monongahela River.Group 4: Larger Rivers where endangered species are expected. These include the Ohio River downstream (DS) of Hannibal Lock and Dam, Little Kanawha River (slack-water section adjoining the Ohio River) and the Kanawha River.These data are based on National Hydrography Dataset (NHD). NHD is a feature-based database that interconnects and uniquely identifies the stream segments or reaches that make up the nation's surface water drainage system. NHD data was originally developed at 1:100,000-scale and exists at that scale for the whole country. This high-resolution NHD, generally developed at 1:24,000/1:12,000 scale, adds detail to the original 1:100,000-scale NHD.
