Summary
Built in 1950, this earth dam stands at a height of 20 feet with a length of 325 feet, providing a storage capacity of 108 acre-feet. The dam features a controlled spillway and a single valve outlet gate, with a low hazard potential and a very high risk assessment rating.
Managed by the Oklahoma Water Resources Board, the Cook dam is regulated and inspected by state authorities to ensure its structural integrity and functionality. Despite its age, the dam has not been rated for its condition assessment, and its last inspection was conducted in December 2010. With the potential for very high risk due to its location and purpose, the Cook dam remains a crucial asset in mitigating flood risks in the area, warranting continued monitoring and maintenance to safeguard the surrounding communities and water resources.
As an essential component of the flood risk reduction infrastructure in Coalgate, Oklahoma, the Cook dam plays a vital role in protecting the local community from potential inundation. With its state-regulated status and operational functionality, the dam serves as a critical barrier against floodwaters, highlighting the importance of ongoing inspection and maintenance to ensure its long-term effectiveness. As water resource and climate enthusiasts, understanding the role of structures like the Cook dam is crucial in promoting sustainable water management practices and resilience against natural disasters in vulnerable regions.

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.
