Scs-Upper Clear Boggy Creek Site-48 Reservoir Report
Last Updated: December 7, 2025
Located in Stonewall, Oklahoma, the SCS-Upper Clear Boggy Creek Site-48 is a state-owned earth dam designed by the USDA NRCS in 1970 for flood risk reduction along Owl Creek.

Summary
Standing at a height of 32 feet with a length of 1500 feet, the dam has a storage capacity of 766 acre-feet and a surface area of 15 acres. With a controlled spillway and a low hazard potential, the dam serves the primary purpose of flood risk reduction in the Pontotoc County area.
Managed by the Oklahoma Water Resources Board (OWRB), the dam is regulated, permitted, inspected, and enforced by the state agency to ensure its structural integrity and safety. Although last inspected in 1980, the dam's condition assessment is currently not rated, and there is no Emergency Action Plan (EAP) prepared. Despite a very high risk assessment, the dam's hazard potential remains low, and further risk management measures are yet to be determined.
Represented in the US Congress by Tom Cole (R), the SCS-Upper Clear Boggy Creek Site-48 is a vital infrastructure contributing to water resource management in Oklahoma. With its earth core and stone foundation, the dam plays a crucial role in mitigating flood risks and protecting the surrounding community from potential inundation events. As climate change impacts become more pronounced, the importance of maintaining and enhancing such water management structures is increasingly recognized by both local and federal authorities.

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.
