Optima Lake is a reservoir in Texas County, Oklahoma. The lake is located near the towns of Hardesty and Guymon in the Oklahoma Panhandle.
The earthen Optima Lake Dam (National ID # OK20510) was constructed in 1978 by the United States Army Corps of Engineers, with a height of 120 feet, and a length at its crest of 16,875 feet.[1] Although designed to contain a maximum of 618,500 acre-feet, the lake has never reached more than 5 percent of its design capacity,[2] and now is effectively empty. Rapid declines in streamflow (related to large-scale pumping from the High Plains Aquifer) coincided with the completion of dam construction[2] to make this lake a dramatic example of unanticipated environmental impacts.[3]
The US Army Corps of Engineers states (emphasis added):
Visitors should be aware that the lake's level can be very low. Depending on rainfall and evaporation rates, the lake may offer no water-based recreation and may not be suitable for swimming, fishing, boating or other activities.[4]
Lake camping facilities and buildings have been dismantled for public safety by the Corps of Engineers as of October 2012.
