Description: WBDHU8: This geospatial dataset represents the 4th level (8-digit) hydrologic unit boundaries of the Watershed Boundary Dataset (WBD) layer for Oregon. It was created by dissolving boundaries from the finer resolution hydrologic units to create these broader boundaries. See metadata for the wbdhu12 feature class for a more complete description of the WBD.
