Summary
The dam, with a height of 35 feet and a length of 900 feet, serves primarily for flood risk reduction along TR-Soldier Creek. It has a storage capacity of 363 acre-feet and a spillway width of 1 foot, with a maximum discharge of 740 cubic feet per second. The dam's hazard potential is deemed significant, with a fair condition assessment as of the last inspection in 2011.
Managed by the OWRB, SCS-Roaring Creek Site-S4 plays a crucial role in protecting the surrounding area from potential flood events, with a very high risk assessment designation. Despite its age, the dam continues to meet state permitting, inspection, and enforcement requirements, demonstrating its ongoing commitment to safety and regulatory compliance. The dam's location in Alex, Oklahoma, highlights its importance in mitigating flood risks and safeguarding the community from potential inundation events.
As a key component of flood risk reduction efforts in the region, SCS-Roaring Creek Site-S4 serves as a valuable infrastructure asset for water resource and climate enthusiasts. Its design and construction by the USDA NRCS, along with state oversight by the OWRB, ensure that the dam continues to fulfill its primary purpose effectively. With a focus on safety and regulatory compliance, this earth dam stands as a testament to the importance of proactive risk management in preserving water resources and protecting communities from the impacts of extreme weather events.

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.
