Summary

Built in 1976 by the USDA NRCS, this earth dam stands at a height of 43 feet with a hydraulic height of 39 feet, primarily serving the purpose of flood risk reduction along Watson Creek. The dam has a storage capacity of 1436 acre-feet and a maximum discharge of 5380 cubic feet per second, with a controlled spillway and one outlet valve.

Despite being classified as having a low hazard potential, the risk assessment for SCS-Lower Clear Boggy Creek Site-25 indicates a very high risk level, prompting further evaluation and potential risk management measures. The dam remains in good condition, with inspections conducted every 5 years since the last assessment in 1980. While the emergency action plan status is not specified, the dam's association with the Natural Resources Conservation Service and its regulatory oversight by the OWRB ensure that necessary measures are in place for the safety and maintenance of this critical flood control infrastructure in Oklahoma.

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.
