54 • (Page 2 . 3-8 ) Twenty-eight potential reservoir sites were identified in five studies conducted between 1969 and 1980. Most of the sites were not seriously considered because of inadequate yield, significant amounts of development in the drainage basin, transmission distance from existing systems, or other circumstances which rendered a site unsuitable for reservoir development. Because the physical characteristics necessary for adequate reservoir development are well known, it is unlikely that any major sites were overlooked. Four of the most promising sites were fully detailed in the 1987 Orange County Water Supply Study. In 1989, the Orange County Commissioners and the Town of Hillsborough Board of Aldermen indicated that a new impoundment on Seven-Mile Creek is the preferred alternative for a new central Orange reservoir. This new impoundment could potentially yield 6 .3 mgd for the Town and other future users. <DELETED>Discussions regarding the planning and management of this " facility , are currently underway. > :.:,::...... �.:: :.:>:.;}::: :<:::.,.;:.:::..:....::::::.;>...:.:::::.::::::::::::.;.:.A .. ...............

This results in potential reservoir yields that are, at best, modest. It is clear that Orange County does not have the sites with a potential to supply large amounts of water over long periods of time. Even with the Cane Creek Reservoir, the County as a whole could face a demand deficit before the year 2010 . The County and individual water suppliers must think in regional terms for planning future long-term sources. Not only do surrounding counties have sites larger than those in Orange County, but joint action among water users can increase the cost effectiveness of source development. Many of these neighboring water supplies have watersheds that begin in Orange County, thus furthering the need for interlocal cooperation. The largest of the sites in neighboring counties is Jordan Lake, with 100 mgd available as a drinking water supply. <DELETED> The allocation process was begun by the Division of Water Resources, NC Department of Natural Resources and Community Development in 1988 <DELETED>. Local governments and agencies in Orange County requested 30. 3 mgd in Level II allocations, which are allocations that would not be used for at least five years. In late 1988, Orange County governments/agencies were allocated a total of 16.0 mgd of this future major supply. The City of Durham 004004 the Little River Reservoir in northern Durham County fiii019109thid supply adds an additional 25 mgd of water to the Durham 'system, more than doubling its capacity. Once filled, the reservoir will give Durham a surplus beyond the year
