Lake Hudson, also known as Markham Ferry Reservoir, is a man-made reservoir in Mayes County, Oklahoma, about 2 miles (3.2 km) northwest of Locust Grove, Oklahoma and 8 miles (13 km) southeast of Pryor, Oklahoma.[1] 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).<ref name="GRDA-KerrDam>GRDA Robert S. Kerr Dam. Retrieved September 19, 2011.</ref>

History

GRDA began construction of the Markham Ferry Dam in December 1961. This was the second of GRDA's hydroelectric projects along the Grand River. The first was Pensacola Dam, which created Grand Lake o' the Cherokees. The Markham Ferry project was completed in April 1964.[1]

Robert S. Kerr Dam structure

The Robert S. Kerr Dam structure is a concrete gravity and earth filled embankment with a concrete ogee weir spillway. The length is 4,494 feet (1,370 m), including the powerhouse,and the height is about 90 feet (27 m) above the stream bed. The spillway has seventeen gates, each 40 by 37 feet (12 by 11 m), operated by two traveling gate hoists. Its capacity is 609,000 cubic feet (17,200 m3) per second.[1]

Lake description

The lake has a surface area of 12,000 acres (49 km2), a shoreline of 200 miles (320 km), and the average elevation of the surface is 619 feet (189 m) above sea level.[2] The normal storage capacity is 200,300 acre feet (247,100,000 m3).[3]

Power generation

The powerhouse has four hydroelectric turbines, providing a total capacity of 114,000 kW. GRDA states that an average year can provide 211 million kWh.[4]

Lake Hudson also is the water source for the nearby Salina Pumped Storage Project..
