Summary
Managed by the Natural Resources Conservation Service, this earth dam was completed in 1965 and stands at a height of 53.4 feet, with a hydraulic height of 51 feet. The reservoir has a storage capacity of 16,351 acre-feet, with a normal storage level of 3,873 acre-feet and a surface area of 405.8 acres.
The dam, situated on Coon Creek, is regulated by the Oklahoma Water Resources Board and is designated as a high hazard potential structure with a Fair condition assessment. With a very high risk assessment rating, the dam is equipped with a controlled spillway and a single slide gate outlet. Although the last inspection took place in 2010, the dam is subject to periodic inspections to ensure its safety and integrity. The site has a significant impact on the local water supply and plays a crucial role in managing water resources in the region.
Overall, SCS-Caney Coon Creek Site-2 serves as a vital infrastructure for water supply purposes in Oklahoma, highlighting the importance of maintaining and monitoring dams to mitigate potential risks and ensure the sustainability of water resources in the face of changing climate conditions. As a key player in the state's water management system, this dam exemplifies the intersection of water resource management and climate resilience, underscoring the need for continued investment and attention to safeguarding critical water infrastructure for future generations.

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.
