Summary

This earth dam stands at a height of 43 feet with a hydraulic height of 40 feet and a length of 1860 feet, providing a storage capacity of 1580 acre-feet. The dam features a controlled spillway and a single valve outlet gate for water release.

Despite being classified as low hazard potential, the risk assessment for this dam site is rated as very high (1), highlighting the importance of regular inspections and maintenance. The dam structure, made of stone core and soil foundation, has not been rated for condition assessment since its last inspection in 1980. While the risk management measures and emergency action plan status are unknown, the dam is state-regulated by the OWRB with permitting, inspection, and enforcement in place.

Water resource and climate enthusiasts will appreciate the historical significance and engineering details of SCS-Cotton-Coon-Mission Cr Site-005 as a flood risk reduction infrastructure in Osage County. With a focus on mitigating potential hazards and ensuring the safety of downstream communities, this dam serves as a critical piece of water management infrastructure in the region, warranting continued monitoring and maintenance to uphold its integrity and functionality for years to come.

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.
