Summary
Completed in 1960, this 23-foot-high dam provides a storage capacity of 855 acre-feet and covers a surface area of 30 acres. With a controlled spillway and a maximum discharge of 3000 cubic feet per second, this low-hazard dam serves as a crucial infrastructure for managing floodwaters in the area.
Despite being rated as "Not Rated" in terms of condition assessment, the dam at SCS-Round Creek Site-1 poses a very high risk, as indicated by its hazard potential and the need for emergency action planning. The dam features a single valve outlet gate and is inspected every 5 years, with the last inspection dating back to January 1, 1980. With a risk management plan yet to be fully developed, the dam's risk assessment highlights the importance of ongoing monitoring and maintenance to ensure the safety and effectiveness of this vital flood control structure.
In the heart of Garvin County, Oklahoma, SCS-Round Creek Site-1 stands as a testament to the collaborative efforts of state agencies like OWRB and federal entities like the Natural Resources Conservation Service. With Congressman Tom Cole representing the district, this earth dam continues to play a pivotal role in protecting the local community from the ravages of flooding while also serving as a reminder of the ongoing challenges faced in managing water resources and climate impacts 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.
