Summary

Built in 1971 by the USDA NRCS, this earth dam stands at a height of 35 feet and spans 450 feet in length. Its primary purpose is flood risk reduction, with a normal storage capacity of 133 acre-feet and a maximum storage of 1687 acre-feet.

Despite being classified as low hazard potential, the dam is considered to have a very high risk due to its location and the potential consequences of failure. The dam is equipped with a controlled spillway and a single valve outlet gate. While the dam has not been inspected since 1980, it is subject to state regulation, inspection, and enforcement by the Oklahoma Water Resources Board.

Water resource and climate enthusiasts will find SCS-Leader-Mid Clr Boggy Cr Site-40 to be a significant structure in the management of flood risk along Coon Creek in Oklahoma. Its design and construction by the USDA NRCS, along with its state regulation and inspection, highlight the importance of maintaining and monitoring such infrastructure to ensure the safety and security of surrounding communities and ecosystems.

Condition Assessment

Satisfactory
No 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

High
Dams 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.
