Grand Lake o' the Cherokees is situated in Northeast Oklahoma in the foothills of the Ozark Mountain Range. It is often simply called Grand Lake. It is administered by the Grand River Dam Authority (GRDA).
The Encyclopedia of Oklahoma History and Culture credits Henry Holderman, a citizen of the Cherokee Nation of Oklahoma as first envisioning Grand River as a source for hydroelectric power for the Cherokee Nation. Even prior to Oklahoma statehood in 1907, Holderman began building political support for such a project. A feasibility study by the Army Corps of Engineers attracted favorable attention in the Oklahoma legislature, leading to creation of the Grand River Dam Authority (GRDA), a state agency, in 1935. Construction began in 1938 on the Pensacola Dam on the Grand River (lower Neosho River) as a Works Progress Administration project. The dam was completed in March 1940, creating the lake behind it. Between 1941 and 1946, the U.S. government took control of Pensacola Dam to divert power to the war effort. Control was returned to the GRDA by the Congress and President Truman amid local celebration in August 1946. [1]
Pensacola Dam is claimed to be the longest multiple arch dam in the world, its main span consisting of 51 arches totaling 5,145 feet (1,568 m) in length, and supporting a walkway and State Highway 28, a narrow two-lane highway. A 120 megawatt, 6-unit powerhouse sits at the west end, with 21 spillways on the east end. [2] The project's chief engineer was W. R. Holway (who was also responsible for Tulsa's Spavinaw water project), while the architect of record for the PWA-style Art Deco design of the dam and powerhouse was Tulsan John Duncan Forsyth. [3] [4] [5] [6]
Another mile east, through the town of Disney, lie two small sister dams known as "the spillways" with an additional 21 gates, surrounded by public parks and launching ramp. 510,000 cubic yards (390,000 m3) of concrete were used in the construction of Pensacola Dam, poured 24 hours a day in just 20 months with Depression-era labor. The lake, and the electric utilities, as well as other projects in the region, along the Grand River are administered by the Grand River Dam Authority, an agency created by the Oklahoma legislature in 1935.
Grand Lake has a surface area of 41,779 [7] acres (169.07 km2) of water, a storage volume of 1,515,416 acre-feet, [7] and 1,366 [8] miles (2,198 km) of shoreline. Unlike other lakes in Oklahoma, Grand Lake is a deep and mostly rocky lake. The average depth for Grand Lake is 36.3 feet. [7] Its mean elevation is 745 [8] ft (227 m) above sea level. [2] In recent years, low fall elevations of 741 were kept by the GRDA to allow millet seeding for migratory waterfowl, resulting in conflict between property owners, environmentalists, and federal agencies. While not expressly built for flood control, Grand Lake contributes to the flood-prone Arkansas River watershed. The Army Corps of Engineers controls releases into the McClellan-Kerr Arkansas River Navigation System when lake levels exceed 745 feet (227 m), although locking into Grand Lake is not possible. Grand Lake and its neighbor, Lake Hudson (also managed by the GRDA), are the only two major lakes in the state where one can build directly on the waterfront.
Residents of the town of Miami and Native American groups have objected to proposals to increase high water levels at Pensacola Dam in order to maintain the water level at Grand Lake. Miami residents are concerned that when water backs up downstream from Miami on the Neosho River, this can contribute to Miami's flooding problems. [9] [10] [11]
The lake is a popular destination for entertainment in the Green Country region. There are a number of shows in the area, as well as resorts, and a sixty-seven-foot long, twin deck paddle wheel riverboat called the Cherokee Queen, [12] which has been in operation since the 1940s. [2] Consistently ranked among the top bass fishing lakes in the United States, Grand also houses a wide variety of other sport and non-sport fishing. Due to its predictable winds, it attracts sailboaters from across the country as well. [2]
Mayes County is a county located in the U.S. state of Oklahoma. As of the 2010 census, the population was 41,259. Its county seat is Pryor Creek. Named for Samuel Houston Mayes, Principal Chief of the Cherokee Nation from 1895 to 1899, it was originally created at the Sequoyah Convention in August 1905.
Lake Overholser is a reservoir within the city limits of Oklahoma City, Oklahoma. Lake Overholser is formed by Overholser Dam on the North Canadian River in Oklahoma County, Oklahoma. The lake is 2.9 miles (4.7 km) west of Bethany. And 4.4 mile from Yukon. Lake Overholser is named after Ed Overholser who was the 16th Mayor of the City of Oklahoma City.
Table Rock Lake is an artificial lake or reservoir in the Ozarks of southwestern Missouri and northwestern Arkansas in the United States. Designed, built and operated by the U.S. Army Corps of Engineers, the lake is impounded by Table Rock Dam, which was constructed from 1954 to 1958 on the White River.
Old Hickory Lock and Dam is a dam located in middle Tennessee on the Cumberland River at river mile 216.2 in Sumner and Davidson Counties, approximately 25 miles (40 km) upstream from Nashville. The reservoir behind the dam is Old Hickory Lake. The dam and lake are named after President Andrew Jackson, who lived in the vicinity at The Hermitage.
The Neosho River is a tributary of the Arkansas River in eastern Kansas and northeastern Oklahoma in the United States. Its tributaries also drain portions of Missouri and Arkansas. The river is about 463 miles (745 km) long. Via the Arkansas, it is part of the Mississippi River watershed. Its name is an Osage word meaning "clear water." The lower section is also known as the Grand River.
Narrows Dam is a dam located 6 miles north of Murfreesboro, Arkansas, that impounds the water of the Little Missouri River (Arkansas) to create Lake Greeson. Narrows Dam was authorized as a flood control and hydroelectric power project by the Flood Control Act of 1941. The dam is a feature of the comprehensive plan for the Ouachita River Basin. Lake Greeson is operated for hydroelectric power, recreation, and flood control.
Denison Dam, also known as Lake Texoma Dam, is a dam located on the Red River between Texas and Oklahoma that impounds Lake Texoma. The purpose of the dam is flood control, water supply, hydroelectric power production, river regulation, navigation and recreation. It was also designated by the American Society of Civil Engineers as a National Historic Civil Engineering Landmark in 1993.
The Nechako Reservoir, sometimes called the Ootsa Lake Reservoir, is a hydroelectric reservoir in British Columbia, Canada that was formed by the Kenney Dam making a diversion of the Nechako River through a 16-km intake tunnel in the Kitimat Ranges of the Coast Mountains to the 890 MW Kemano Generating Station at sea level at Kemano to service the then-new Alcan aluminum smelter at Kitimat. When it was constructed on the Nechako River in 1952, it resulted in the relocation of over 75 families. It was one of the biggest reservoirs built in Canada until the completion of the Columbia Treaty Dams and the W.A.C. Bennett Dam that created Lake Williston. The water level may swing 10 feet between 2790 and 2800 feet.
Watauga Dam is a hydroelectric and flood control dam on the Watauga River in Carter County, in the U.S. state of Tennessee. It is owned and operated by the Tennessee Valley Authority, which built the dam in the 1940s as part of efforts to control flooding in the Tennessee River watershed. At 318 feet (97 m), Watauga is the second-highest dam in the TVA river and reservoir system, and at the time of its completion was one of the highest earth-and-rock dams in the United States. The dam impounds the TVA Watauga Reservoir of 6,430 acres (2,600 ha), and its tailwaters feed into Wilbur Lake.
Cherokee Dam is a hydroelectric dam located on the Holston River in Grainger County and Jefferson County, Tennessee, in the southeastern United States. The dam is operated and maintained by the Tennessee Valley Authority, which built the dam in the early 1940s to help meet urgent demands for energy at the outbreak of World War II. Cherokee Dam is 175 feet (53 m) high and impounds the 28,780-acre (11,650 ha) Cherokee Lake. It has a generating capacity of 136 megawatts. The dam was named for the Cherokee, a Native American tribe that controlled much of East Tennessee when the first European settlers arrived in the mid-18th century.
South Holston Dam is a hydroelectric and flood control dam on the South Fork Holston River in Sullivan County, in the U.S. state of Tennessee. It is the uppermost of three dams on the South Fork Holston owned and operated by the Tennessee Valley Authority, which built the dam in the 1940s as part of efforts to control flooding in the Tennessee River watershed. On October 21, 1950 the valve gate closed and water began backing up to create South Holston Reservoir. Work began on the dam in December 1941, but in November 1942, the War Production Board requested that the operation be suspended because of a shortage of critical materials. Work did not resume until July 1, 1947. The dam now impounds the South Holston Lake of 7,550 acres (3,060 ha), which extends northeastward across the Tennessee-Virginia state line.
John Redmond Reservoir is a reservoir on the Neosho River in eastern Kansas. Built and managed by the U.S. Army Corps of Engineers, it is used for flood control, recreation, water supply, and wildlife management. It borders the Flint Hills National Wildlife Refuge to the northwest.
Glen Canyon Dam, a concrete arch dam on the Colorado River in the American state of Arizona, is viewed as carrying a large amount of risk, most notably due to siltation. The Colorado and San Juan rivers deposit large volumes of silt into Lake Powell, slowly decreasing its capacity. The sediment will eventually build up against the dam and could affect its safe operation and lead to its failure.
Pine Creek Lake is a lake in McCurtain County and Pushmataha County, Oklahoma, USA. It is 8 miles (13 km) north of Valliant, Oklahoma. It is located east of Rattan and north of Sobol.
The Grand River Dam Authority (GRDA) is an agency of the state of Oklahoma created to control, develop, and maintain the Grand River waterway. It was created by the Oklahoma state legislature in 1935, and is headquartered in Tulsa, Oklahoma. GRDA was designed to be self-funding from the sales of electricity and water. The state of Oklahoma was to provide no funding from taxes. The Authority was authorized to issue revenue bonds to fund large-scale capital investments.
William Rea Holway, commonly known as W. R. Holway, was an American civil engineer who became prominent in Oklahoma. He is best known for his work on major water supply projects for the city of Tulsa, and on the Pensacola Dam at Grand Lake o' the Cherokees.
The Pensacola Dam, also known as the Grand River Dam, is a multiple-arch buttress dam located between the towns of Disney and Langley on the Grand River in Mayes County, Oklahoma. The dam is operated by the Grand River Dam Authority and creates Grand Lake o' the Cherokees. After decades of vision and planning, it was constructed between 1938 and 1940 for the purposes of hydroelectric power generation, flood control and recreation. It is Oklahoma's first hydroelectric power plant and is referred to as the longest multiple-arch dam in the world.
Lake Hudson, also known as Markham Ferry Reservoir, is a man-made reservoir in Mayes County, Oklahoma, United States, about 2 miles (3.2 km) northwest of Locust Grove, Oklahoma and 8 miles (13 km) southeast of Pryor, Oklahoma. It was created by the completion of the Robert S. Kerr Dam on the Grand River in 1964. It is managed by the Grand River Dam Authority (GRDA).
The Salina Pumped Storage Project is a 260-megawatt (350,000 hp) pumped-storage power station near Salina, Oklahoma. It is owned and operated by the Grand River Dam Authority (GRDA). Its construction was in response to growing power demands and a lack of dam sites on the Grand River. The first phase was completed in 1968 and the second in 1971. The upper reservoir for the power station is Lake W. R. Holway which was built on Saline Creek and the lower reservoir is Lake Hudson on the Grand River. During periods of lower power demand, water is pumped from Lake Hudson to Lake Holway and released back down through the pump-generators during periods of high energy demand.
Council Grove Lake is a reservoir on the Neosho River in east-central Kansas. Built and managed by the U.S. Army Corps of Engineers, it is used for flood control, recreation, and water supply.
