Summary

Completed in 1959, this dam primarily serves the purpose of flood risk reduction along the TR-Washita River. With a height of 31 feet and a storage capacity of 277 acre-feet, the dam covers a surface area of 14 acres and has a controlled spillway with a width of 1 foot.

Despite being classified as having a low hazard potential, the risk assessment for SCS-Dead Indian-Wldhorse Cr Site-08 indicates a very high risk level. However, the condition assessment remains unrated, as the last inspection took place in 1980. The dam is equipped with a single valve outlet gate and is under the jurisdiction and regulation of the Oklahoma Water Resources Board (OWRB). The site is situated within the Tulsa District of the US Army Corps of Engineers, with Congressman Frank D. Lucas representing the region.

Water resource and climate enthusiasts interested in the engineering and management of dams will find SCS-Dead Indian-Wldhorse Cr Site-08 a fascinating subject of study. The dam's design, construction, and ongoing regulatory oversight provide valuable insights into flood risk reduction strategies in the region. As efforts to assess and mitigate the high-risk potential associated with the dam continue, there is a growing need for updated inspections and risk management measures to ensure the safety and integrity of this critical water resource infrastructure.

Condition Assessment

Satisfactory
No existing or potential dam safety deficiencies are recognized. Acceptable performance is expected under all loading conditions (static, hydrologic, seismic) in accordance with the minimum applicable state or federal regulatory criteria or tolerable risk guidelines.
Fair
No existing dam safety deficiencies are recognized for normal operating conditions. Rare or extreme hydrologic and/or seismic events may result in a dam safety deficiency. Risk may be in the range to take further action. Note: Rare or extreme event is defined by the regulatory agency based on their minimum
Poor A dam safety deficiency is recognized for normal operating conditions which may realistically occur. Remedial action is necessary. POOR may also be used when uncertainties exist as to critical analysis parameters which identify a potential dam safety deficiency. Investigations and studies are necessary.
Unsatisfactory
A dam safety deficiency is recognized that requires immediate or emergency remedial action for problem resolution.
Not Rated
The dam has not been inspected, is not under state or federal jurisdiction, or has been inspected but, for whatever reason, has not been rated.
Not Available
Dams for which the condition assessment is restricted to approved government users.

Hazard Potential Classification

High
Dams assigned the high hazard potential classification are those where failure or mis-operation will probably cause loss of human life.
Significant
Dams assigned the significant hazard potential classification are those dams where failure or mis-operation results in no probable loss of human life but can cause economic loss, environment damage, disruption of lifeline facilities, or impact other concerns. Significant hazard potential classification dams are often located in predominantly rural or agricultural areas but could be in areas with population and significant infrastructure.
Low
Dams assigned the low hazard potential classification are those where failure or mis-operation results in no probable loss of human life and low economic and/or environmental losses. Losses are principally limited to the owner's property.
Undetermined
Dams for which a downstream hazard potential has not been designated or is not provided.
Not Available
Dams for which the downstream hazard potential is restricted to approved government users.
