Summary
Completed in 1956, this dam stands at a height of 33 feet with a hydraulic height of 24 feet and a length of 1250 feet. It has a storage capacity of 273 acre-feet and a normal storage of 52 acre-feet, serving the primary purpose of flood risk reduction. The dam features a controlled spillway and one outlet valve.
Despite being classified as having a low hazard potential, SCS-Cobb Creek Site-006 is considered to be at very high risk due to its condition assessment being not rated. The last inspection date dates back to January 1, 1980, with an inspection frequency of 5 years. While the emergency action plan status and risk management measures are undisclosed, the dam has not been modified over the years and does not have any associated structures. With the oversight of the OWRB as the state regulatory agency, this dam plays a crucial role in managing the water resources in Caddo County, Oklahoma, highlighting the importance of maintaining and monitoring its structural integrity for the safety of the surrounding community.

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.
