Summary
Completed in 1973, this dam stands at a height of 40 feet with a hydraulic height of 38 feet, serving the primary purpose of flood risk reduction. With a normal storage capacity of 55 acre-feet and a maximum storage capacity of 128 acre-feet, this dam covers a surface area of 7 acres and has a controlled spillway type with a width of 1 foot.
Despite being classified with a low hazard potential, the risk assessment for SCS-Rush Creek Site-023 highlights a very high risk rating, emphasizing the importance of regular inspections and maintenance. The dam is equipped with a valve outlet gate and has not been rated for its current condition, with the last inspection conducted in 1980. While emergency action plans and risk management measures are not specified, the dam is subject to state permitting, inspection, and enforcement by the Oklahoma Water Resources Board.
Overall, SCS-Rush Creek Site-023 serves as a vital infrastructure for flood control in Grady County, Oklahoma, under the regulatory oversight of the OWRB. With its strategic location along Rush Creek and its significant role in reducing flood risks, this dam underscores the importance of effective water resource management and climate resilience efforts in the region.

Condition Assessment
SatisfactoryNo 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
HighDams 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.
