Get to Know Your Watersheds
A watershed is a land area that funnels water down to a common low point. When it rains or snows, water flows from higher elevations down to lower elevations, carrying with it the pollutants on the ground.
Watersheds can be as big as an entire river basin or as small as a tiny creek area. In Chapel Hill, we are in the Jordan Lake watershed, which is part of the Cape Fear River Basin. We have several subwatersheds throughout Town. Learn more below.

Chapel Hill is located in North Carolina's Cape Fear River Basin. It is the largest of the state's 17 river basins, and the only North Carolina river basin that flows directly into the ocean. The Cape Fear River is formed by the Haw, Deep, and Rocky Rivers, which meet in Chatham County below Jordan lake.

Jordan Lake supplies drinking water to approximately half a million people; provides habitat to one of the largest populations of bald eagles on the east coast; and offers recreational opportunities such as swimming, boating and fishing. Yet Jordan Lake is not a healthy body of water and needed rules to improve its water quality and to protect human and animal life. Learn more by clicking on the links below.
History
"B. Everett Jordan Dam and Lake (Jordan Lake) are under the stewardship of the U.S. Army Corps of Engineers (USACE), Wilmington District. The Jordan Lake project, originally known as New Hope project is located in Chatham County, North Carolina, 2.4 miles northeast of Moncure and 25 miles southwest of Raleigh on the Haw River in the upper Cape Fear River Basin.
Jordan Lake was authorized by Public Law 88-253, enacted by the 88th Congress on 30 December 1963. House Resolution 8667 authorized the project in accordance with the recommendations of the Chief of Engineers in House Document 508, Eighty-seventh Congress. The approved report recommended construction of an earthen dam with a multi-level Intake Tower in the interest of flood control, water supply, water-quality control, recreation, and other purposes.While hydropower was considered as a potential project purpose in early studies, it was later dropped because of local dissention. Navigation was never considered as a project purpose.
A contract to initiate construction was awarded on November 5, 1970 and after considerable litigation, construction was completed and Lake first reached normal pool level of elevation 216.0 feet mean sea level (msl) on February 4, 1982."

The headwaters of Bolin Creek are located northwest of Homestead Road and Old NC86, north of Carrboro. Bolin Creek is approximately 11 miles long, with about half of its 12 square mile watershed within the Town's jurisdiction. The watershed includes a variety of residential areas, Carrboro's downtown commercial district, much of Chapel Hill's downtown business district, the commercial district along Estes Drive and University Place, and approximately 146 acres of the University of North Carolina-Chapel Hill campus.

The Booker Creek Watershed is approximately 6.3 square miles and five subwatersheds. It is composed primarily of residential (single-family and multi-family) and commercial land uses. The commercial land uses are concentrated along Martin Luther King, Jr. Boulevard, Weaver Dairy Road, East Franklin Street, and Fordham Boulevard.
There are two private lakes in Booker Creek - Lake Ellen and Eastwood Lake - and several smaller ponds scattered throughout the watershed.

Current Subwatershed Studies

Map of Little Creek Watershed (PDF)
Bolin and Booker Creeks merge to form Little Creek on the east side of Town, near the end of Emory Drive and east of Rainbow Soccer Fields. Little Creek flows into the Upper New Hope Arm of Jordan Lake.
Much of Little Creek’s water quality is influenced by upstream activities in the watersheds of Bolin Creek and Booker Creek. But what dominates the biology of the creek is the geologic area it flows through: the Triassic Basin. This is an old valley that has filled in with fine silts and clays.
Streams flowing through this area have very different characteristics than those elsewhere in the Piedmont, different enough that the NC Division of Water Quality (DWQ) does not have an index for rating biological conditions in Triassic Basin streams. Little Creek and small tributaries in the Triassic Basin have very shallow slopes, slow-moving water, and habitats more characteristic of coastal lowlands than do streams in the rocky Piedmont.
Recreation
Little Creek Bottomlands and Little Creek Waterfowl Impoundment: Federal property in this area is leased to the State of North Carolina and is designated by the North Carolina Wildlife Resources Commission (NCWRC) as Permanent Wildlife Lands and managed as game lands. In addition, this area is managed as a waterfowl sub-impoundment and is open to public hunting and fishing by licensed individuals in accordance with all NCWRC Inland Fishing, Hunting, and Trapping Regulations.

Morgan Creek originates near Pickard's Mountain, in a rural area west of Chapel Hill, and falls approximately 300 feet over a 17-mile run as it flows to Jordan Lake. It is the major tributary to University Lake, a drinking water supply for Chapel Hill and Carrboro. Downstream of University Lake, Morgan Creek flows through residential areas in the southern parts of Carrboro and Chapel Hill, along UNC's Finley Golf Course, and through the NC Botanical Garden's Mason Farm Biological Reserve. Major tributaries of Morgan Creek within the Town's jurisdiction include Fan Branch and Wilson Creek.
University Lake
University Lake was constructed by UNC-Chapel Hill as a drinking water reservoir in 1932 by damming Morgan Creek. It holds 450 million gallons and has a 213 acre surface area, with a watershed spanning 30 square miles. Morgan Creek and its tributaries (Phils Creek, Neville Creek, Price Creek and Pritchards Mill Creek) feed the lake. Orange Water and Sewer Authority (OWASA) owns and manages the lake as a primary drinking water source for Carrboro and Chapel Hill.

Recreation
Much of the land along Morgan Creek is conserved and maintained by the NC Botanical Garden and the NC Botanical Garden Foundation. Some of these areas are open to the public; other areas have restricted use. Please respect restrictions and private property as you plan your outings.

Many small streams on the eastern side of Chapel Hill flow to New Hope Creek, which flows into the Upper New Hope Arm of Jordan Lake. Those include Old Field Creek in the Eubanks Road vicinity, Dry Creek, partially located behind East Chapel Hill High School, and the stream leading from Clark Lake off Pope Road on the Durham border. A portion of New Hope Creek’s watershed is in Durham.
