Lake Lone Chimney owned by the Tri-County Development Authority, is in Pawnee County, Oklahoma, east of Glencoe. The lake, whose dam is also known as Lower Black Bear Creek Watershed Dam 19M, also extends into southern Payne County, Oklahoma. It was built in 1980 by the Tri-County Development Authority, Pawnee County Conservancy District and the Black Bear Conservancy District, assisted by the Oklahoma Conservation Commission and the USDA Natural Resources Conservation Service (NRCS) Watershed Protection and Flood Protection Program.
The dam was originally designed as part of a regional flood control project of the Lower Black Bear Creek Watershed, which included nineteen flood control dams. During the period of 1935-1954, before the dams were built, there had been seven major floods and 73 smaller floods.
Before the Lone Chimney Lake was built, the design was altered to include 4,212 acre feet (5,195,000 m3) of municipal water storage. The lake became the primary source of water for the small communities of Glencoe, Morrison, Yale, Blackburn, Skeede, Maramec and Terlton, Oklahoma. It is a secondary source for the larger towns of Cleveland and Pawnee, Oklahoma.
According to one official website, the lake surface covers an area of 550 acres (2,200,000 m2). It has a shoreline of 17 miles (27 km). The Oklahoma Water Resources Board states that the shoreline is 18 miles (29 km), the normal surface area is 518 acres (2,100,000 m2), water capacity is 5,722 acre feet (7,058,000 m3), and the normal elevation is 939 feet (286 m) above sea level.
Lone Chimney Lake has been plagued by drought-related problems for nearly a decade. It was nearly drained of municipal water in 2006, when high consumption caused the fixed intake valve to be above the lake's surface. It had to be replaced with a floating valve. The cost was about $19,000, but allowed the lake management to continue supplying its customers.
