Scs-Round Creek Site-2 Reservoir Report
Last Updated: December 7, 2025
SCS-Round Creek Site-2, located in Garvin, Oklahoma, is a state-regulated earth dam constructed in 1960 by the USDA NRCS to reduce flood risks along the Rounds Creek.

Summary
The dam stands at a height of 30 feet and has a storage capacity of 546 acre-feet, with a normal storage level of 87 acre-feet. It is designed to control a maximum discharge of 2340 cubic feet per second, with a controlled spillway width of 1 foot.
Despite being rated as having a low hazard potential, the risk assessment for SCS-Round Creek Site-2 indicates a very high risk level due to its location and potential impact on surrounding areas in case of a breach. The dam is equipped with a valve outlet gate and is inspected every 5 years, with the last recorded inspection date dating back to 1980. The condition assessment is currently not rated, and there is no Emergency Action Plan (EAP) prepared for this structure at the moment.
Overall, SCS-Round Creek Site-2 serves as a crucial flood risk reduction infrastructure in the area, with its design and construction overseen by the Natural Resources Conservation Service. Despite its low hazard potential, the dam's high risk assessment underscores the importance of regular inspections and potential updates to ensure the safety and security of the surrounding community and environment.

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.
