Eufaula Dam is a dam across the Canadian River in Oklahoma. Completed in 1964, it impounds Eufaula Lake, one of the world’s largest man-made lakes, covering 102,500 acres (41,500 hectares). The dam serves to provide flood control, water supply, navigation and hydroelectric power generation. It supports a 90 MW power station.^[1] 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 in July that year, the first generator was operational. By September, the other three generators were operational.^[2]

State Highway 71 runs across the top of the dam.

Fishing at Eufaula Dam

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.^[3]
