Summary
Built in 1974, this earth dam stands at a height of 31 feet and has a maximum storage capacity of 82 acre-feet. It serves the primary purpose of "Other" and is regulated by the Oklahoma Water Resources Board. The dam is situated on TR-CAVALRY CREEK and is under the jurisdiction of the state.
With a low hazard potential and a very high risk assessment rating, Oknoname 149009 poses a significant risk to the surrounding area in the event of a failure. Despite being in operation for several decades, the dam's condition assessment is marked as "Not Rated" and it has not been inspected since 2006. Emergency preparedness measures such as an Emergency Action Plan (EAP) are not documented, raising concerns about the safety and security of the structure.
Water resource and climate enthusiasts may find Oknoname 149009 to be an intriguing case study in dam management and regulation. The dam's design, construction, and maintenance history, as well as its risk assessment and emergency preparedness status, offer valuable insights into the challenges faced in ensuring the safety and integrity of critical infrastructure in the face of evolving environmental conditions and regulatory requirements.

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.
