Chickasha Lake

Chickasha Lake, also known as Lake Chickasha, is a man-made reservoir in the central part of the state of Oklahoma. Located in Caddo County, Oklahoma, it was completed in 1958. The main purposes were supplying water and for recreation. The lake is about west of Chickasha, and is owned and operated by that city.
A 2011 survey showed that the lake has a surface area of a capacity of of water when filled to an elevation of. The mean depth was and the maximum depth was. It also has 10 miles of shoreline.
The lake is fed by multiple streams, but primarily Spring Creek on the west arm and Stinking Creek on the east arm.

Spring Creek

The Spring Creek that feeds Lake Chickasha originates east of Salyer Lake and just south of Oklahoma State Highway 152 in Caddo County. It travels generally south and slightly to the east until impounded by the lake. Spring Creek then continues at the south end of the lake, traveling south-southeast to its mouth on the Washita River.
This creek is not to be confused with at least five other creeks in Oklahoma with the “Spring Creek” name, nor with numerous other watercourses named Spring Creek in other states and countries.

Stinking Creek

Stinking Creek originates east of Spring Creek and south of SH-152, at a point south of Cogar, Oklahoma. It flows generally south for 12 miles through Caddo County until impounded at Lake Chickasha. It does not continue past the lake.
Despite the name, the water in Stinking Creek was found in 2012 to have improved enough to meet state dissolved oxygen criteria for support of warm-water aquatic communities, after implementation of best management practices in the watershed.
