This data was created as part of the Missouri Aquatic Gap Project. 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 into distinct stream valley segment types according to a number of variables including temperature, stream size, flow, geology, relative gradient, valley wall interaction (a surrogate for potential bluff pool habitat), stream size discrepancy, floodplain reach, and channel type. This dataset was resticted to those stream segments that touched the Ozark National Scenic Riverways jurisdiction boundary or other public lands adjacent to the Ozark National Scenic Riverways. 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.
