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.

Contents

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.

Construction

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 / 35.65417; -79.06667 (B. Everett Jordan Dam) 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.

Water supply

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).

Water quality

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]

Jordan Lake offers a variety of facilities for recreation, conservation, and flood control. B. Everett Jordan Lake Map.png

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]

Shoreline trash cleanup

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]

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.

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 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.

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.
