Summary
Built in 1960, this earth dam stands at a height of 24 feet and has a length of 670 feet, providing a storage capacity of 240 acre-feet. The dam serves various purposes, including flood control and water supply management, with a controlled spillway and a low hazard potential.
Managed by the Oklahoma Water Resources Board, A C M undergoes regular state inspections and enforcement to ensure its structural integrity and safety. Despite being classified as low risk, the dam is rated as very high in terms of risk assessment, highlighting the importance of ongoing monitoring and risk management measures. The dam's emergency action plan status and inundation maps are currently not available, signaling a need for enhanced preparedness in the event of an emergency.
For water resource and climate enthusiasts, A C M presents an intriguing case study in dam management and risk assessment. Situated within the Tulsa District of Oklahoma, this dam stands as a crucial infrastructure for the local community, emphasizing the significance of sustainable water resource practices and the need for proactive measures in mitigating potential risks associated with dam failure. As climate change continues to impact water availability and extreme weather events, the management of dams like A C M becomes increasingly vital in ensuring the resilience of 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.
