Summary
Completed in 1998, this earth dam stands at 35 feet tall with a length of 1100 feet, providing a maximum storage capacity of 1049 acre-feet. With a hazard potential rated as high and a condition assessment marked as fair, this dam is subject to regular inspections by the OWRB to ensure its safety and effectiveness in managing floodwaters in the area.
The dam features a controlled spillway and a single valve outlet gate, with a maximum discharge capacity of 8706 cubic feet per second. Its primary purpose is flood risk reduction, serving as a crucial infrastructure for water resource management in Washington County, Oklahoma. Despite being a state-owned structure, it is not funded or operated by any federal agency, highlighting the collaborative effort between state and local authorities to safeguard the community from potential flooding events. With a risk assessment rating of very high, this dam plays a critical role in mitigating flood risks and protecting the surrounding areas from water-related disasters.
As water resource and climate enthusiasts, the SCS-Cotton-Coon-Mission Creek Sit-006 dam serves as a fascinating case study in sustainable infrastructure development and risk management in the face of changing climate patterns. Its location along the Caney River and its high hazard potential underscore the importance of proactive measures in maintaining and monitoring dams to ensure their functionality and safety. With ongoing inspections and state regulatory oversight, this dam exemplifies the collaborative efforts needed to address water resource challenges and adapt to the evolving climate conditions in Oklahoma.

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.
