Summary
This earth dam stands at 28 feet in height, with a hydraulic height of 25 feet and a length of 3950 feet. It has a storage capacity of 272 acre-feet and a normal storage volume of 47 acre-feet, serving a surface area of 12 acres.
Despite being classified as having a low hazard potential, the dam at SCS-Cottonwood Creek Site-02 has a very high risk assessment rating of 1. Although last inspected in 1980, it is equipped with a controlled spillway and a single valve outlet gate. The dam's condition remains unrated, and it lacks an emergency action plan or updated contact information. While the risk management measures and inundation maps are yet to be prepared, the dam continues to play a crucial role in mitigating flood risks for the surrounding area.
Given its strategic location and vital role in flood risk reduction, SCS-Cottonwood Creek Site-02 serves as a crucial infrastructure asset in Logan County, Oklahoma. With its historical significance dating back to the 1960s and ongoing state regulatory oversight, the dam remains a key component of the local water resource management system. As efforts continue to enhance its safety and emergency preparedness measures, the dam stands as a testament to the intersection of water resource management and climate resilience in the region.

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.
