Summary
With a dam height of 25 feet and a length of 1050 feet, the earth dam structure is owned by the state and under the jurisdiction of the Oklahoma Water Resources Board. The dam has a normal storage capacity of 35 acre-feet and a maximum discharge of 1070 cubic feet per second, serving as a crucial water resource management infrastructure in the region.
The dam's hazard potential is classified as low, but it is recognized as having a very high risk rating based on the risk assessment. Although the condition assessment is currently not rated, the dam has not undergone any modifications since its completion. The emergency action plan (EAP) status and risk management measures for the dam are not specified in the available data. Despite the lack of recent inspection records, the dam's design and purpose for flood risk reduction highlight its significance in managing water resources and mitigating potential hazards in the area, making it a key asset for climate and water resource enthusiasts to monitor and study.
With a controlled spillway and a valve outlet gate, the SCS-Upper Clear Boggy Creek Site-20 dam represents a vital piece of infrastructure in the water resource management system of Oklahoma. Its proximity to the city of Olney and the Fort Worth District underscores its importance in safeguarding against flooding events in the region. As climate change continues to impact water resources and increase the frequency of extreme weather events, understanding and monitoring the condition of dams like SCS-Upper Clear Boggy Creek Site-20 become crucial for ensuring the safety and resilience of communities and ecosystems in the face of changing climatic conditions.

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.
