DeGray Lake is a reservoir on the Caddo River in Arkansas, 8 miles (13 km) from Arkadelphia. Arkansas Scenic Byway 7 is located on the eastern shore of the lake, and provides views of the lake, and also places to stay. DeGray Lake Resort State Park was opened in 1974 to encourage tourism and recreation on DeGray Lake.
A reservoir is, most commonly, an enlarged natural or artificial lake, pond or impoundment created using a dam or lock to store water.
The Caddo River is a tributary of the Ouachita River in the U.S. state of Arkansas. The river is about 82 miles (132 km) long.
Arkansas is a state in the southern region of the United States, home to over 3 million people as of 2018. Its name is of Siouan derivation from the language of the Osage denoting their related kin, the Quapaw Indians. The state's diverse geography ranges from the mountainous regions of the Ozark and the Ouachita Mountains, which make up the U.S. Interior Highlands, to the densely forested land in the south known as the Arkansas Timberlands, to the eastern lowlands along the Mississippi River and the Arkansas Delta.
The documented history of the DeGray area dates back to AD 700 when the area was inhabited by the Caddo Indians. Hernando de Soto then came and explored this area in 1541, after discovering hot springs. The Caddo Indians' way of life was changed forever when coming in contact with the Spanish explorers; the Indians were introduced to the horse. In the 18th century French fur trappers brought trade to the area with their extensive trapping methods. DeGray Lake was in fact named after a French fur trader, DeGraff, who settled this region. Several artifacts have been found near the dam site, and many have been brought to a local university, Henderson State University.
Henderson State University (HSU) is a public liberal arts university in Arkadelphia, Arkansas. Founded in 1890 as Arkadelphia Methodist College, it is Arkansas's only member of the Council of Public Liberal Arts Colleges. Henderson's curricula based on the belief that a liberal arts education is essential for all undergraduates; Henderson utilizes a program based on a core of courses in the arts and sciences. The school owns and operates radio station KSWH-FM, as well as the local Public-access television cable TV channel, HTV on Suddenlink's channel 9.
DeGray lake and dam were authorized by Congress in the River and Harbor Act of 1950. Congress passed the Water Supply Act of 1958, which provided for the inclusion of municipal and industrial water supply as one of the project purposes. Construction on the dam began in 1962 and was completed in 1972 at a cost of $63,800,000. A 40 MW hydraulic turbine and a 28 MW turbine generate electricity for the Southwestern Power Administration of Arkansas, Texas, and Oklahoma. DeGray dam impounds the waters of the Caddo River to form a flood control lake that covers 13,400 acres (5,400 ha), and a shoreline of 207 miles (333 km).
The Southwestern Power Administration (Southwestern) is an agency of the U.S. Department of Energy. Southwestern's mission was established by Section 5 of the Flood Control Act of 1944. The agency is a power marketing administration responsible for marketing the hydroelectric power produced at 24 United States Army Corps of Engineers multipurpose dams. By law, the power and associated energy are marketed to publicly held entities such as rural electric cooperatives and municipal utilities. Southwestern has over one hundred such "preference" customers which ultimately serve over 8 million end use customers.
Texas is the second largest state in the United States by both area and population. Geographically located in the South Central region of the country, Texas shares borders with the U.S. states of Louisiana to the east, Arkansas to the northeast, Oklahoma to the north, New Mexico to the west, and the Mexican states of Chihuahua, Coahuila, Nuevo León, and Tamaulipas to the southwest, while the Gulf of Mexico is to the southeast.
Oklahoma is a state in the South Central region of the United States, bordered by Kansas on the north, Missouri on the northeast, Arkansas on the east, Texas on the south, New Mexico on the west, and Colorado on the northwest. It is the 20th-most extensive and the 28th-most populous of the fifty United States. The state's name is derived from the Choctaw words okla and humma, meaning "red people". It is also known informally by its nickname, "The Sooner State", in reference to the non-Native settlers who staked their claims on land before the official opening date of lands in the western Oklahoma Territory or before the Indian Appropriations Act of 1889, which dramatically increased European-American settlement in the eastern Indian Territory. Oklahoma Territory and Indian Territory were merged into the State of Oklahoma when it became the 46th state to enter the union on November 16, 1907. Its residents are known as Oklahomans, and its capital and largest city is Oklahoma City.
Many of the long-time residents recall families in the area who were "bought out" in order to fill area behind the dam. Residents were offered money for their property, so that the lake could be built. The eventual damming of the Caddo River forced many people to move elsewhere in the area. Brick and concrete structures from former homesteads still stand on the bottom of the lake.
Beaver Lake is a man-made reservoir in the Ozark Mountains of Northwest Arkansas and is formed by a dam across the White River. Beaver Lake has some 487 miles (784 km) of shoreline.
