Summary
Built in 1960, this earth dam stands at 25 feet tall and stretches 300 feet in length, with a maximum storage capacity of 50 acre-feet. The dam serves a primary purpose of "Other" and is regulated by the Oklahoma Water Resources Board, with state permitting, inspection, and enforcement in place. While the hazard potential is considered low, the risk assessment ranks it as very high, indicating the need for careful monitoring and management.
Despite its relatively low hazard potential, Oknoname 037013 poses a significant risk due to its location and potential impact on the surrounding area. The dam's controlled spillway, with a width of 1 foot, is designed to handle a maximum discharge of 1200 cubic feet per second. The dam's condition assessment is marked as "Not Rated," suggesting a need for further evaluation and potential maintenance. While the emergency action plan status is not specified, the risk management measures and inundation maps preparedness are unknown, highlighting a potential area for improvement in disaster preparedness.
In the event of an emergency, the contact information for the dam is outdated, raising concerns about the effectiveness of communication and response protocols. With a frequency of inspection every 5 years, it is crucial to ensure that the dam's structural integrity and safety measures are regularly assessed and updated. Overall, the data for Oknoname 037013 underscores the importance of proactive risk management and emergency preparedness to safeguard water resources and mitigate potential climate-related threats in the region.

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.
