Summary
With a height of 40 feet and a length of 1800 feet, this dam has a storage capacity of 1769 acre-feet and a maximum discharge of 4560 cubic feet per second. Despite being classified as having a low hazard potential, it is considered to have a very high risk due to its age and the lack of recent condition assessments.
The dam features a controlled spillway with a width of 1 foot and is equipped with a single valve outlet gate for water release. Although it is not currently rated for condition, the dam has not had any modifications since its construction and has not undergone a formal emergency action plan (EAP) evaluation. With the risk of inundation looming and the lack of updated emergency protocols, there is a need for increased monitoring and maintenance to ensure the safety and integrity of this vital flood control structure in Grady County, Oklahoma.
Water resource and climate enthusiasts will find SCS-Round Creek Site-7 to be a fascinating case study of a mid-century earth dam with a complex history of state oversight and federal agency involvement. As discussions around dam safety and risk management continue to evolve, this site serves as a reminder of the importance of proactive maintenance and emergency planning to protect communities and water resources from the potential consequences of dam failures.

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.
