Description: Hydro 24K - 2006 dataset. Contains Unnamed Tributeries (UT). The North Carolina Center for Geographic Information and Analysis, in cooperation with the North Carolina Division of Water Quality, developed this digital hydrography dataset with Use Support information to enhance planning, siting and impact analysis. These files enable users to identify surface water features which have special restrictions for building and development based on the locations of the features and their water quality classifications. Surface waters consist of streams, rivers, lakes, ponds, reservoirs, and shorelines. This file also enables users to determine whether a particular surface water is meeting its intended water quality use and to what extent. The linework is based on the USGS 1:24,000-scale Digital Line Graphs but has had additions from other sources as needed to include the hydrographic features in the stream classification codes. This statewide coverage is stored by river basin. The data are updated as changes occur.
