The current protection measures go above and beyond the state minimum standards for WS -2, and Critical Watershed designation would provide recognition of that fact. 11. UPPER ENO BASIN CLASSIFICATION As previously stated, the preliminary classification of the Eno River basin treats all portions of the basin in the same manner. There are significant differences, however, between sub - basins in the Eno River.- These difference range from density of existing development to location of existing and future water supplies. There are three existing water bodies (two serving as supplies) and three proposed water supplies in the Upper and Middle Eno basins. There are no water supplies existing or proposed in the Lower Eno basin, with the exception of the City of Durham's emergency water intake on the Eno. The future disposition of this emergency water source is currently being discussed by Durham County and Durham City. Historically and to this day, Orange County has separated this basin into the "Upper Eno ", located north and west of Lake Ben Johnson in Hillsborough; and the "Lower Eno ", from Lake Ben Johnson to the Durham County line. As such, watershed protection measures similar to that of the proposed WS -III classification have been applied to the zoned portions of the Upper Eno basin since 1984. Recent policy discussion on the implications of Interstate 85/40 and the Efland community have led the County to add a third sub -basin to reflect the different character of the "Middle Eno", from Corporation Lake to Lake Ben Johnson. In its preliminary watershed classifications, NCDEM has recommended a classification of WS -IV for the entire basin.
