Keystone Lake is a reservoir in northeastern
Oklahoma on the Arkansas
and Cimarron rivers. It is located upstream about 23 miles
(37 km) from Tulsa. It was created in 1968 when the Keystone
Dam was completed. The primary purposes are: flood control,
hydroelectric power generation, wildlife management and recreation.

Keystone Lake is about 23,600 acres (96 km2) in area, and was
designed to contain 505,381 acre feet (623,378,000 m3) of
water. It was named for the community of Keystone, which existed on
the site from 1900 until 1962, when it was inundated by the waters of
the lake.[a] Construction of the lake forced the relocation of three
other towns: Mannford,
Oklahoma (also known as New Mannford by
locals), Prue (also known as New Prue), and Appalachia Bay, Oklahoma.
The town of Osage was partially abandoned to the lake, while the rest
clings to the south shore. Engineers built a levee around low-lying
areas of the south and east sides of Cleveland,
Oklahoma to prevent
flooding of that city. The shoreline extends for 330 miles
Oklahoma state parks, Keystone State Park and Walnut Creek State
Park, are located along the shores of the lake offering camping,
hiking and biking trails, fishing, swimming and boating opportunities.
The area also features a Yogi Bear's Jellystone Park Camp-Resort as
you cross the Keystone Dam near Sand Springs.
Keystone Lake project was authorized by the Flood Control Act of
1950. It was designed and built by the Tulsa District, Army Corps of
Engineers. Construction began in January 1957 and was complete for
flood control purposes in September 1964. Commercial operation of the
power generating facility began in May 1968.
A reregulating dam, located 7.8 miles (12.6 km) downstream of the
main dam, was also completed in 1968. Cost of the total project was
approximately $123 million. In 1986, the reregulating dam was removed
due to public safety issues, as 16 people had drowned at the dam.
Dam construction details
The dam was actually constructed across the Arkansas River, downstream
of the confluence with the Cimmaron River. It is built of rolled
earthfill material. Maximum height of the dam is 121 feet (37 m)
above the stream bed. The total length of the dam is 4,600 feet
(1,400 m), including a 1,600 feet (490 m)-long concrete
section. The spillway in the concrete section is 856 feet (261 m)
wide. The non-overflow part of the concrete section includes a power
intake structure. State Highway 151 crosses the dam, connecting State
Highway 51 on the south with U.S. Highway 64 on the north.
The spillway is a gated ogee weir, 720 feet (220 m) wide with
eighteen tainter gates, each 40 by 35 feet (12 by 11 m). Spillway
capacity at the maximum pool level (elevation 766.0 feet
(233.5 m)) is 939,000 cubic feet per second (26,600 m3/s).
Capacity at the top of the flood control pool level (elevation 754.0
feet (229.8 m)) is 565,000 cubic feet per second
(16,000 m3/s). The spillway also has nine sluices, each 5.67 by
10 feet (1.73 by 3.05 m).
The power intake structure is between the spillway and the left
non-overflow section of the dam. It includes two penstocks, each 27
feet (8.2 m) diameter and controlled by two 14 by 30 feet (4.3 by
9.1 m) gates. The power generation facility includes two
hydroelectric generators, each rated at 35,000 kW

In September and October 1986,
Keystone Lake was filled to capacity
when the remnants of Hurricane Paine entered
Oklahoma and dropped
nearly 22 inches (0.56 m) of water into the Cimmaron and Arkansas
rivers northwest of the lake, requiring the Corps of Engineers to
release water downstream at a rate of 310,000 cubic feet per second
(8,800 m3/s), which made downstream flooding inevitable. As a
result, a private levee in West Tulsa failed, causing more than $1.3
million in damages.
View of Keystone Lake
According to the Corps of Engineers website,
Keystone Lake has 16
recreational areas (including 3 alcohol-free beaches), 11 boat ramps,
4 marinas and 2 off-road vehicle areas. There are also campgrounds, a
waterfowl refuge and a public hunting area. Keystone State Park nearby
offers cabins. Fishing is popular, with the most plentiful species
being striped bass, sand bass, black bass, small mouth bass, crappie,
and catfish. Fauna around the lake include: white-tailed deer,
raccoon, bobcat, coyote, beaver, squirrel, cottontail rabbit, quail,
dove, ducks and geese. Hunting and fishing licenses are regulated by
Oklahoma and Federal laws.
