Summary

Completed in 1978, this earthen dam stands at a height of 25 feet, with a hydraulic height of 21 feet and a structural height of 25 feet. The dam has a storage capacity of 212 acre-feet and a normal storage of 39 acre-feet, serving to regulate the flow of the TR-DRY CREEK river or stream.

Managed by the Oklahoma Water Resources Board, this dam has a low hazard potential and has not been rated for its current condition. Despite its age, the dam's risk assessment is very high, signaling the need for ongoing monitoring and potential risk management measures. The last inspection date recorded was in 1980, with a recommended inspection frequency of every 5 years to ensure the dam's continued safety and effectiveness in flood control.

Located in the city of Addington, SCS-Cow Creek Site-44 is a key infrastructure asset in flood prevention efforts in the region. With its controlled spillway and valve outlet gates, the dam plays a crucial role in reducing flood risk and protecting downstream areas. As climate change intensifies and water resources become increasingly precious, the proper maintenance and management of sites like SCS-Cow Creek Site-44 are essential to ensuring the safety and resilience of communities in the face of changing environmental conditions.

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.
