B. Everett Jordan Lake is a reservoir in New Hope Valley, west of Cary and south of Durham in Chatham County, North Carolina, in the United States; the northernmost end of the lake extends into southwestern Durham County.
Part of the Jordan Lake State Recreation Area, [1] the reservoir covers 13,940 acres (5,640 ha) with a shoreline of 180 miles (290 km) at its standard water level of 216 feet (66 m) above sea level. Empounded in 1974, it was developed as part of a flood control project prompted by a particularly damaging tropical storm that hit the region downstream in September 1945. Constructed at an original cost of US$146,300,000, it is owned and operated by the United States Army Corps of Engineers, which dammed and flooded the Haw River and New Hope River between 1973 and 1983.
The Jordan Lake Dam (also known as the B. Everett Jordan Project and the New Hope Dam) is located at 35°39′15″N79°4′0″W / 35.65417°N 79.06667°W 4 miles (6.4 km) upstream from the mouth of the Haw River in the upper Cape Fear River drainage basin. Completed in 1974 by the Nello L. Teer Company, it is 1,330 feet (410 m) in length and has a top elevation of 266.5 feet (81.2 m) above mean sea level. [1]
During the construction of the reservoir, much of the area was permanently changed. The Durham and South Carolina Railroad was relocated from the New Hope basin to higher ground but its stations were not rebuilt, and the line itself was soon abandoned. [2] Many farming families were relocated as the project was developed and several roads in eastern Chatham County were either rerouted or taken out of commission completely. Some of the roads were never demolished, but simply allowed to flood over. When the lake is at low water volume, many of these roads can still be seen and some have even been utilized for makeshift boat ramps. [3]
Originally authorized in 1963 as the New Hope Lake Project, the reservoir was renamed in 1974 in memory of B. Everett Jordan, former US Senator from North Carolina.
Jordan Lake serves as a major water supply for central North Carolina. Allocations made in Round 4 total 95.9% of the water supply pool. Governmental units allocated water from Jordan Lake in Round 4 (approved by the NC EMC on March 9, 2017) include the system jointly operated by Towns of Cary and Apex, which also serves Morrisville and the Wake County portion of Research Triangle Park (46.2%); Chatham County North (13%); City of Durham (16.5%); Town of Holly Springs (2%); Orange County (1.5%); Orange Water & Sewer Authority (5%); City of Raleigh (4.7%); Town of Pittsboro (6%). [4] [5] However, in 2019, following the fourth round of allocations the City of Raleigh relinquished its 4.7% water supply pool allocation. As such it is expected that the remaining unallocated portion of the water supply pool is 8.8%.
Previously, allocations made in 2002 totalled 63 mgd (1% is often assumed to be equal to 1 mgd, but allocations are officially by percentage of the total water supply pool). Governmental units allocated water from Jordan Lake at that time were the Towns of Cary and Apex (32 mgd), Chatham County (6 mgd), City of Durham (10 mgd), Town of Holly Springs (2 mgd), Town of Morrisville (3.5 mgd), Orange County (1 mgd), Orange Water & Sewer Authority (5 mgd), and Wake County - RTP South (3.5 mgd). [6] [7] [8]
Jordan Lake was declared as nutrient-sensitive waters (NSW) by the North Carolina Environmental Management Commission from 1983, the year it was impounded. The lake is eutrophic or hyper-eutrophic owing to excessive nutrient levels. [9]
Requirements of the federal Clean Water Act were triggered when the lake became impaired, including the need to set load reduction limits for point and nonpoint sources and enforce discharge limits. [10]
The Jordan Lake Rules are designed to improve water quality in the lake. The rules were developed with extensive meetings, public hearings and negotiations between residents, environmental groups, local and state government agencies and other stakeholders. The rules mandate reducing pollution from wastewater discharges, stormwater runoff from new and existing development, agriculture and fertilizer application. [11] [12]
From July 2011 several NC laws have been passed delaying and weakening the rules, culminating in a plan to deploy floating arrays of in-lake circulators intended to reduce harmful algae and excessive chlorophyll. [13] [14] However, they proved ineffective in a testing program and were removed in 2016.
On December 21, 2017, researchers at Duke University have discovered elevated levels of several perfluorinated compounds an unregulated family of industrial chemicals including some that can raise cancer risks in Jordan Lake and drinking water treated by the town of Cary. Cary water treatment officials, who have independently confirmed the findings of Duke researchers, say the town's water is safe to drink. They also point out that the compounds detected are still below health advisory levels set by the U.S. Environmental Protection Agency. Testing still continues as of March 8, 2018. [15]

Swimming and boating are permitted in the lake.
Bald eagle habitat being endangered by trash submerged by the lake's creation spurred volunteer efforts to clean up the shoreline and other sensitive areas. [16] [17]
In 2009 the U.S. Army Corps of Engineers worked with local activists to establish Clean Jordan Lake, a nonprofit "friends of the lake" group. [18] [19] Volunteer cleanups aided by the Corps of Engineers began in 2010. [20] [21] Since then, Clean Jordan Lake has organized over 300 community service cleanups, formed the Adopt-A-Shoreline Program that comprises 19 groups that clean habitually littered areas three times per year, and formed the Adopt-A-Feeder Stream Program with semi-annual cleanups to prevent trash from reaching the lake. As of late 2017, 5,600 volunteers have removed 13,500 bags of trash (enough to fill 40 large dumpsters) and 4,300 tires. Clean Jordan Lake estimates that 80% of the trash is from stormwater runoff and 20% from recreational use of the lake. [22] [23]
Cary is a town in Wake, Chatham, and Durham counties in the U.S. state of North Carolina and is part of the Raleigh-Cary, NC Metropolitan Statistical Area. According to the 2020 census, its population was 174,721, making it the seventh-most populous municipality in North Carolina, and the 148th-most populous in the United States. In 2023, the town's population had increased to 180,010.
The American Tobacco Trail (ATT) is a 22.6-mile (36.4 km) long Rails-to-Trails project located in the Research Triangle region of North Carolina, running along an abandoned railroad bed originally built for the American Tobacco Company in the 1970s. The route crosses through portions of Durham County, Chatham County, and Wake County. The ATT is part of the East Coast Greenway and is open to pedestrians, cyclists, equestrians and other non-motorized users.
The Haw River is a tributary of the Cape Fear River, approximately 110 mi (177 km) long, that is entirely contained in north central North Carolina in the United States. It was first documented as the "Hau River" by John Lawson, an English botanist, in his 1709 book "A New Voyage to Carolina." The name is shortened from Saxapahaw, from the Catawban /sak'yápha:/, "piedmont, foothill", from /sak/, "hill", plus /yápha:/, "step". The river gives its name to a small town that formed on its banks.
Jordan Lake State Recreation Area is a North Carolina state park spanning Chatham County, and Wake County, North Carolina. It comprises 4,558 acres (18.45 km2) of woodlands along the shores of 13,940-acre (56 km2) Jordan Lake.
Pyramid Lake is a reservoir formed by Pyramid Dam on Piru Creek in the eastern Topatopa Mountains, near Castaic, Southern California. It is a part of the West Branch California Aqueduct, which is a part of the California State Water Project. Its water is fed by the system after being pumped up from the San Joaquin Valley and through the Tehachapi Mountains.
Lake Isabella also called Isabella Lake, is a reservoir in Kern County, California, United States created by the earthen Isabella Dam. At 11,000 acres (4,500 ha), it is one of the larger reservoirs in California. Lake Isabella is located about 40 miles (64 km) northeast of Bakersfield, and is the main water supply for that city. It was formed in 1953 when the U.S. Army Corps of Engineers dammed the Kern River at the junction of its two forks. The area is in the southern end of the Sierra Nevada range and the lake itself is located in low mountains at an elevation of approximately 2,500 ft (760 m) where summer temperatures reach over 100 °F (38 °C) but low enough to avoid winter snows on the surrounding ridges. The former towns of Isabella and Kernville were flooded when the reservoir was created.
Lake Lanier is a reservoir in the northern portion of the U.S. state of Georgia. It was created by the completion of Buford Dam on the Chattahoochee River in 1956, and is also fed by the waters of the Chestatee River. The lake encompasses 38,000 acres (15,000 ha) or 59 sq mi (150 km2) of water, and 692 mi (1,114 km) of shoreline at normal level, a "full pool" of 1,071 ft (326 m) above mean sea level and the exact shoreline varies by resolution according to the coastline paradox. Named for Confederate veteran and poet Sidney Lanier, it was built and is operated by the U.S. Army Corps of Engineers for flood control and water supplies. Its construction destroyed more than 50,000 acres (20,000 ha) of farmland and displaced more than 250 families, 15 businesses, and relocated 20 cemeteries along with their remains in the process.
The California Department of Water Resources (DWR) is part of the California Natural Resources Agency and is responsible for the management and regulation of the State of California's water usage. The department was created in 1956 by Governor Goodwin Knight following severe flooding across Northern California in 1955, where they combined the Division of Water Resources of the Department of Public Works with the State Engineer's Office, the Water Project Authority, and the State Water Resources Board. It is headquartered in Sacramento.
New Hope Creek is a watercourse that rises in rural Orange County, North Carolina, in the United States. It drains the western portion of Orange County and the southern half of Durham County and flows into the northern end of Jordan Lake reservoir. The drainage area encompasses urban, suburban and rural lands. Formerly the New Hope River, it was a tributary of the Cape Fear River until it was dammed to create Jordan Lake. Construction of the lake began in 1973, after a comprehensive study of regional water management by the U.S. Army Corps of Engineers, motivated by major flooding in a 1945 hurricane. Several communities draw drinking water from Jordan Lake, increasing interest in protection of the New Hope Creek watershed.
The Washington Suburban Sanitary Commission is a bi-county political subdivision of the State of Maryland that provides safe drinking water and wastewater treatment for Montgomery and Prince George's Counties in Maryland except for a few cities in both counties that continue to operate their own water facilities.
Isabella Dam is an embankment dam located in the Kern River Valley, about halfway down the Kern River course, between the towns of Kernville and Lake Isabella in Kern County, California.
New Hogan Lake is an artificial lake in the foothills of the Sierra Nevada in Calaveras County, California, about 30 miles (48.3 km) northeast of Stockton. It is formed by New Hogan Dam on the Calaveras River, whose North and South forks combine just upstream of the lake, and has a capacity of 317,000 acre⋅ft (391,000,000 m3). The earth-fill dam, completed in 1963, is 210 feet (64.0 m) high from the crest of the dam to the original streambed. The reservoir was first filled in 1965. There is a small hydroelectric plant at its base. It is owned by the United States Army Corps of Engineers and provides flood protection, drinking water, electricity and water for irrigation. There is also recreation available, such as boating, fishing, water skiing and camping.
Canyon Lake is a reservoir on the Guadalupe River in the Texas Hill Country in the United States. Canyon Lake is a U.S. Army Corps of Engineers reservoir formed on the Guadalupe River in Comal County by Canyon Dam, which is located about sixteen miles northwest of New Braunfels. The dam, lake, and all adjacent property are managed by the U.S. Army Corps Of Engineers. Water rights, waste water treatment, and hydroelectric generating facilities are managed by the Guadalupe-Blanco River Authority. Construction of the dam began in 1958 and was completed in 1964. The reservoir serves to provide flood control and water supply for the communities downstream from the dam. The lake is also a popular recreational destination.
Lake Mendocino is a large reservoir in Mendocino County, California, northeast of Ukiah. It covers 1,922 acres (7.78 km2) and was formed by the construction of Coyote Valley Dam in 1958. The lake and dam provide flood control, water conservation, hydroelectric power, and recreation. The dam also includes a fallout shelter built during the Cold War era to protect against the radiation from nuclear attacks from the Soviet Union.
Lake Michie is a reservoir in central North Carolina, within the Neuse River watershed. The lake is located in northern Durham County near the town of Bahama. Fed principally by the Flat River, Lake Michie is the primary reservoir for the city of Durham. The reservoir dam was completed in 1926.
The Culmback Dam is a large rockfill hydroelectric and water supply dam on the Sultan River, a tributary of the Skykomish River, in Washington. Built in 1965, the dam is 640 feet (200 m) long at the crest and 262 feet (80 m) high. Its reservoir, Spada Lake, provides water for 70 to 75 percent of Snohomish County and feeds the Jackson Hydro Project, providing 112 megawatts of clean energy to Snohomish county. Some critics charge that the dam has strongly impacted the runs of salmon and other migratory fish in the Sultan River by depleting gravel and sediment needed to line the riverbed. The dam's operator counters that Culmback Dam dramatically reduces flooding events, benefiting fish populations and the surrounding communities. The dam was named in honor of George Culmback, a former mayor of Everett. Spada Lake is a reference to the character Count Spada in The Count of Monte-Cristo.
Hunter Lake is a proposed 2,649-acre (10.72 km2) reservoir to be created in Illinois, United States, by damming Horse Creek, a tributary of the Sangamon River. If the lake is built, its construction would flood a section of bottomland in southeastern Sangamon County, Illinois near the city of Springfield, between two other lakes, Lake Springfield and Lake Sangchris, to an elevation of 568.7 feet above sea level. See, http://supplementalwater.cwlp.com/Documents.aspx p. 2-22. The lake is a project of City Water, Light & Power, the local municipal electric utility.
Patroon Creek is a stream in Albany County, New York, United States and is a tributary of the Hudson River which flows south to New York Harbor and the Atlantic Ocean. The creek's source is Rensselaer Lake in the western section of the city of Albany. Patroon Creek received its name from the patroon of Rensselaerswyck.
The tri-state water dispute is a 21st-century water-use conflict among the U.S. states of Georgia, Alabama, and Florida over flows in the Apalachicola-Chattahoochee-Flint River Basin and the Alabama-Coosa-Tallapoosa River Basin. The U.S. Army Corps of Engineers has regulated water flow for the entire Chattahoochee River, from Lake Lanier in Forsyth County, Georgia, to Alabama and Florida.
There are a large number of reservoirs in Wales reflecting the need for the supply of water for both industry and for consumption, both within the country itself and in neighbouring England. A number also provide hydroelectricity and many old reservoirs also provided motive power for industries, especially for the processing of minerals such as metal ores and slate.
