Scs-Upper Clear Boggy Creek Site-17 Reservoir Report
Last Updated: December 6, 2025
Located in Coal County, Oklahoma, the SCS-Upper Clear Boggy Creek Site-17 is a state-regulated earth dam designed by the USDA NRCS in 1961 for flood risk reduction along the TR-Clear Boggy Creek.

Summary
Standing at 17 feet high and spanning 1300 feet in length, this dam has a storage capacity of 157 acre-feet and serves as a controlled spillway with a maximum discharge capacity of 740 cubic feet per second. Despite its low hazard potential, the dam has a very high risk assessment rating of 1, highlighting the importance of regular inspections and maintenance to ensure its structural integrity.
The primary purpose of the SCS-Upper Clear Boggy Creek Site-17 is flood risk reduction, and it is owned by the state of Oklahoma with oversight from the OWRB. Although the dam is currently in a not rated condition assessment status, its emergency action plan (EAP) status is unknown, and there is no recorded risk management measures in place. With only one valve outlet gate, this dam may benefit from updated inspection and maintenance practices to mitigate potential risks and ensure its effectiveness in flood control for the surrounding area.
As a key infrastructure for managing water resources in the region, the SCS-Upper Clear Boggy Creek Site-17 plays a crucial role in protecting the community from flooding events. With its historical completion in 1961, this earth dam continues to provide valuable flood protection, but its high risk assessment underscores the need for ongoing monitoring and maintenance to safeguard its functionality and resilience in the face of changing climate conditions and potential emergencies.

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.
