This coverage contains selected arcs from the 1:100,000 National Hydrography Dataset (NHD) that was developed by the USGS and EPA. The selected arcs represent the centerlines of wide streams, impoundments, reservoirs, and wetlands as well as the segments of single line streams. An Arc/Info macro was run on the arc segments to pull select attributes from various NHD tables and attach them directly to the arc component. These stream segments have been classified according to a number of variables including temperature, stream size, flow, geology, soil texture, relative gradient, valley wall interaction (a surrogate for potential bluff pool habitat), stream size discrepancy, and channel type. This dataset was resticted to those stream segments that touched the Buffalo National River jurisdiction boundary or other public lands adjacent to the Buffalo National River. Additionally, tributaries to the mainstem river were cut when they crossed the floodplain of the mainstem river. This allowed these segments to be coded as "floodplain" segments.
