Eufaula Lake is a reservoir in Oklahoma. It is located on the Canadian River, 27 mi (43 km) upstream from its confluence with the Arkansas River and near the town of Eufaula. The lake covers parts of McIntosh County, Pittsburg, Haskell and Okmulgee counties and drains 47,522 square miles (123,080 km2). Water sources include the Canadian, North Fork Canadian and Deep Fork rivers. It is the largest-capacity lake in the state of Oklahoma with a volume of 2,099,000 acre feet (2.589×109 m3), a surface area of 102,000 acres (410 km2) and 600 miles (970 km) of shoreline.
Congress approved construction of the dam and lake in 1946 to provide flood control, hydroelectric power, water supply, navigation and recreation. The U. S. Army Corps of Engineers began construction of the 975 meter-long (3,199 feet) Eufaula Dam wall in 1956 and was completed in 1964. President Lyndon B. Johnson came to Oklahoma to dedicate the dam on September 25, 1964. The dam holds back a lake area of over 412 square kilometres (159 sq mi). The hydroelectric power station was designed to provide 90,000 kilowatts of electric power from the lake waters.
According to the Corps of Engineers in 2015, the Eufaula project cost $121.4 million, and has prevented nearly $575.5 million in flood damages since its completion.The lake attracts about 2.5 million visitors every year.
Heavy rains in the spring of 2015, caused Eufaula Lake to rise so rapidly that the Corps of Engineers to open the flood gates and release water at rates as high as 48,000 cubic feet (1,400 m3) per second. This was the highest rate since 1990.
Eufaula Dam is east of the city of Eufaula, Oklahoma. It is 3,200 feet (975 m) long and 114 feet (35 m) high. It is constructed with an earthen embankment and concrete. The associated hydroelectric power plant has three turbines, each rated at 30 megawatts, for a total installed capacity of 90 megawatts The dam was approved by the Rivers and Harbors Act of 1946 and construction began in 1956. In February 1964, the river was closed and The generators went operational in September 1964.State Highway 71 runs across the top of the dam.
