Summary
Completed in 1960, this earth dam stands at a height of 30 feet and spans a length of 910 feet, providing a maximum storage capacity of 357 acre-feet. The dam is situated on TR-Larimore Creek and is under the jurisdiction of the Oklahoma Water Resources Board, with state permitting, inspection, and enforcement in place to ensure its safety and compliance.
With a low hazard potential and a very high risk assessment ranking, SCS-Round Creek Site-4 is equipped with a controlled spillway and one valve outlet gate. Although the dam's condition assessment is currently not rated, it undergoes inspections every 5 years, with the last one conducted in 1980. While an emergency action plan (EAP) is not listed as being prepared or updated, measures for risk management and inundation mapping are not outlined. Despite these factors, the dam serves as a crucial infrastructure for flood risk mitigation in the Grady County area.
Water resource and climate enthusiasts will find SCS-Round Creek Site-4 to be an essential component of Oklahoma's flood control infrastructure, with its strategic location on TR-Larimore Creek and its significant storage capacity. As a state-regulated structure with low hazard potential, this dam underscores the importance of proactive monitoring and upkeep to ensure its continued effectiveness in reducing flood risks for the surrounding community. The collaboration between the USDA NRCS, the Oklahoma Water Resources Board, and other relevant agencies highlights the commitment to maintaining the safety and functionality of this vital water resource management system.

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.
