Summary
Standing at 42 feet high with a hydraulic height of 38 feet, this dam serves the primary purpose of flood risk reduction, with a storage capacity of 237 acre-feet and a normal storage capacity of 66 acre-feet. The dam has a surface area of 13 acres and a maximum discharge capacity of 1275 cubic feet per second, making it a crucial structure for managing water resources in the area.
Despite being classified as low hazard potential, the risk assessment for SCS-Rush Creek Site-039a indicates a very high risk level, emphasizing the importance of proper monitoring and maintenance. The dam features a controlled spillway with a width of 1 foot and a single valve outlet gate for water release. The condition of the dam is currently listed as "Not Rated," with the last inspection conducted in 1980 and a scheduled inspection frequency of every 5 years. With the dam under state jurisdiction and permitting, as well as enforcement by the OWRB, it plays a vital role in water resource management and climate resilience efforts in Garvin County, Oklahoma.
In the event of an emergency, it is crucial for stakeholders to ensure that an Emergency Action Plan (EAP) is in place and meets the necessary guidelines to effectively respond to any potential risks or incidents. As the dam continues to play a key role in flood risk reduction along Rush Creek, maintaining its structural integrity and adherence to regulations is essential for protecting lives and property downstream. With a dedicated focus on risk management measures and ongoing assessments, SCS-Rush Creek Site-039a remains a critical component of water resource infrastructure in the region.

Dam Data Reference
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.
