Lake Chickasha is a 1,370-acre reservoir located in Caddo County, Oklahoma between Chickasha and Anadarko. Originally constructed in 1958 to supply water to the City of Chickasha, the lake is now primarily a recreational facility due to high sulfate concentrations from underlying gypsum deposits making it unsuitable for drinking water. The reservoir features relatively clear water with a depth averaging around 48 feet at its deepest point. Fed by Spring and Stinking Creeks, Lake Chickasha is considered a hypereutrophic lake with high productivity, resulting in an excellent fishery that offers year-round angling opportunities. The lake provides recreational activities like fishing, boating, camping, and hunting, generating revenue for the local community.
