City of Stigler

PROJECT PURPOSE

Dam rehabilitation to mitigate deficiencies in the areas of slopes, stability, seepage or spillway conveyance. Work will be done on the City of Stigler water supply lake completed in 1939. The dam consists of an earthen embankment approximately 1860 feet long with a maximum height of 40 feet. The dam was rated in poor condition according to USDA and OWRB condition rating systems in 2021. Funding will be used to repair and rehabilitate the dam to mitigate deficiencies the area of slope, stability, seepage and spillway conveyance.

EVIDENCE

The City of Stigler has engaged the Engineering firm of Freese and Nichols of Curtis, Texas to complete a comprehensive report to include, Project management, Field Investigations, Engineering Analysis and Observation, Evaluation and report. A draft report will be submitted to the City of Stigler outlining alternatives to mitigate deficiencies in the dam and a recommendation for mitigation made. The City of Stigler will pay the cost of this study to Freese and Nichols. The contract amount is $351,580.00.

POPULATION DESCRIPTION

Haskell County will benefit from this program. Haskell County and Stigler will have to raise the retail and wholesale cost of water to pay the remediation cost. The City of Stigler cannot calculate impact until we know the cost. Haskell County has a 20% Native American population and routinely in the top 5 in unemployment rates, annual income and poverty rates.

PERFORMANCE MEASURING

Control of the leaks and other mediation measures will be measured and inspected by the City of Stigler's Engineering firm, OWRB and FEMA. Before and after measurements of the dam performance will be a major basis for measurement of remediation success. Annual inspections are required to confirm dam performance after repairs are made. Other performance measures will be project completion schedule and performance to budget.
