资源简介：
The Watershed and Subwatershed hydrologic unit boundaries (WSB)provide a uniquely identified and uniform method of subdividing large drainage areas. The smaller sized 6th level sub-watersheds (up to 250,000 acres) are useful for numerous application programs supported by a variety of local, State, and Federal Agencies.
