Summary
Completed in 1980, this earth dam stands at a height of 23 feet, with a storage capacity of 484 acre-feet and a normal storage level of 73 acre-feet. The dam spans a length of 2200 feet and has a controlled spillway with a width of 1 foot.
The dam, situated on Brush Creek in Washington County, Oklahoma, is under the regulatory authority of the Oklahoma Water Resources Board (OWRB) and undergoes state inspections, permitting, and enforcement. With a high hazard potential and a very high risk assessment rating, this structure plays a crucial role in mitigating flood risks in the area. Despite not having a condition assessment, the dam is equipped with a valve outlet gate and operates under the supervision of the Natural Resources Conservation Service.
As a key component of flood risk management in the region, SCS-Cotton-Coon-Mission Cr Site-007 serves as a vital infrastructure for water resource and climate enthusiasts. Its strategic location and design features make it an essential asset in safeguarding communities and properties from potential inundation events. With its history dating back to the 1980s, this dam continues to play a pivotal role in protecting the surrounding area from the impacts of extreme weather events and ensuring water resource sustainability in the region.

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.
