Summary
Completed in 1962, this dam stands at a height of 35 feet with a hydraulic height of 33 feet, serving a primary purpose of flood risk reduction. With a storage capacity of 50 acre-feet and a maximum discharge of 500 cfs, this controlled spillway dam plays a crucial role in managing water flow in the region.
Despite its low hazard potential, SCS-Rush Creek Site-103 poses a very high risk due to its age and lack of recent condition assessments. The dam features a single valve outlet gate and has not undergone modifications or inspections since January 1980, raising concerns about its structural integrity and emergency preparedness. While the dam is not owned or funded by federal agencies, it is subject to state regulation and inspection by the Oklahoma Water Resources Board, highlighting the importance of ongoing monitoring and maintenance to ensure its effectiveness in mitigating flood risks.
As water resource and climate enthusiasts, the unique characteristics of SCS-Rush Creek Site-103 offer insights into the challenges and opportunities of dam infrastructure in managing water resources and addressing climate-related risks. By understanding the design, purpose, and condition of this dam, stakeholders can actively engage in discussions about the importance of maintaining and improving critical water infrastructure to safeguard communities and ecosystems in the face of changing environmental conditions.

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.
