MSDI Framework Hydrologic Units
Abstract This data set contains hydrologic unit boundaries at the Watershed (5th-Code) level. The data set was developed by delineating the boundary lines on 1:100,000 scale base maps or overlays and digitizing the delineated lines. 5th-code number assignment is subject to change in 4th-code units that span state boundaries as final 5th-code boundaries are developed for North Dakota, South Dakota, and Wyoming. This dataset is distributed with a companion layer dissolved from it, called Subbasin_1999, that contains the 4th-code sub-basins.
Purpose The watershed hydrologic unit boundary provides a uniquely identified and uniform method of subdividing large drainage areas. These smaller sized hydrologic units (approximately 40,000 to 250,000 acres) are useful in many programs supported by the Natural Resources Conservation Service and others.
