14 the Professional Engineer Summer 2014 Jordan Lake: A history of regulatory action J ordan Lake has been the focus of environmental management activities by a number of state and local government bodies. Tese include: a focus of assessment activities by the N.C. Department of Environment and Natural Resources; the Environ- mental Management Commission developing rules requiring some of the most stringent controls for nutrients, specifcally total nitrogen and total phosphorus, in the country for point-source discharges, stormwater discharges for new develop- ment, existing urban developments and other nonpoint sources; legislative oversight by the General Assembly, which modifed and delayed the Jordan Lake Rules on several occasions; and proactive activity by several units of local government in terms of both land use regulation and improvements to water discharge sources. Te purpose of this article is to highlight some of the history and regulatory actions to protect this lake and potential next steps in the management eforts. Regulatory history Te U.S. Congress authorized New Hope Reservoir in 1963 in response to severe fooding in the Cape Fear River Basin, from Moncure to Elizabethtown after a hurricane in 1946, and a subsequent study by the U.S. Army Corps of Engineers. Te authorization listed its purposes as food control, water supply, recreation and protecting downstream water quality. Construction of the impoundment began in the late 1960s but was delayed as a result of litigation by the North Carolina Conservation Council and upstream communities, which were concerned about the potential for extremely poor water quality of the lake. During this time, Congress changed the reservoir's name to B. Everett Jordan Dam and Lake. Te litigation was dismissed in 1977 and the reservoir was impounded in September 1981 and completely flled in early 1982. UNC Chapel Hill researchers conducted detailed water-quality monitoring of the lake for the frst three years under contract to Corps of Engineers. While the lake was highly eutrophic, early predictions of extremely poor water quality were not accurate. Jordan Lake was initially classifed as Class C waters — protected for secondary recreation and aquatic life — because these were the classifcations of the portions of New Hope Creek, Haw River and tributaries that were impounded.
