Stigler Municipal Improvement Authority (SMIA), located in Stigler, Oklahoma, will construct a domestic drinking water supply system to serve rural residents of the city of Stigler.

Stigler, a rural city with a population of 2,703, will provide backup emergency supplies to Haskell County, approximately 9,000 additional residents.

The entire SMIA service area is rural and located within the boundary of the Choctaw Nation of Oklahoma.

Currently, all water available to SMIA is moved through Stigler Lake.

The dam at Stigler Lake replacement is classified by the state as a high hazard potential due to uncontrolled seepage and severe deterioration of the downstream slope.

Failure of the dam would eliminate the city's entire water supply, resulting in significant property damage and possible loss of life, and would have devastating impacts on the local economy.

The proposed project will raise the dam crest, flatten the downstream slope, add a toe drain to provide hydraulic and slope stability, upgrade the existing spillway, and install a seepage barrier cutoff system.

The project will also install new buried pipeline to convey water from Lake John Wells feeder lake to Stigler Lake directly to the Stigler Lake Water Treatment Plant, creating a much-needed redundancy in the water system.

The dam is a priority project listed in Stigler's local hazard mitigation plan and is supported by the Choctaw Nation.
