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.
Construction of the lake forced the relocation of three other towns:
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 (530 km).
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/
