Summary

This earth dam stands at a height of 23 feet with a length of 950 feet and a storage capacity of 317 acre-feet. Despite having a low hazard potential, the dam's risk assessment is classified as very high, indicating the importance of proper management and maintenance.

Owned by the state and regulated by the Oklahoma Water Resources Board, this dam features a controlled spillway and a single valve outlet gate for water release. While the condition assessment is not rated, inspections are conducted every five years, with the last recorded inspection dating back to 1980. The emergency action plan status, risk management measures, and inundation maps are not currently available, highlighting potential areas for improvement in emergency preparedness.

With a risk level of very high and a history dating back to the 1960s, SCS-Bear-Fall & Coon Creek Site-020 serves as a critical infrastructure for flood control in Logan County, Oklahoma. As enthusiasts of water resources and climate, understanding the details of this dam's design, construction, and current status is vital for ensuring its continued effectiveness in protecting the surrounding community from potential flooding events.

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.
