Summary
Built in 1959 by SCHNABEL, this Earth dam stands at a height of 80 feet and spans a length of 11,850 feet along the Cobb Creek. With a primary purpose of flood risk reduction, the dam has a storage capacity of 14,200 acre-feet and serves to protect the surrounding area from potential flooding.
Managed by the Oklahoma Water Resources Board, SCS-Cobb Creek Site-001 is regulated, permitted, inspected, and enforced by the state. The dam has a high hazard potential and a very high risk assessment rating, making it crucial for emergency preparedness and risk management measures to be put in place. Despite its age, the dam's condition is yet to be rated, highlighting the importance of ongoing monitoring and maintenance to ensure its structural integrity and safety.
With a controlled spillway and a maximum discharge capacity of 58,200 cubic feet per second, SCS-Cobb Creek Site-001 plays a vital role in managing water flow and mitigating flood risks in the Washita County area. As a key infrastructure asset in the region, the dam serves as a critical component of the local water resource management system, safeguarding communities and properties from the impacts of extreme weather events.

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.
