Summary
The dam serves multiple purposes and has a storage capacity of 57 acre-feet, with a maximum discharge of 85 cubic feet per second. Despite being rated as having low hazard potential, it is considered to have a very high risk due to its condition assessment not being rated and lacking emergency action plans.
While the dam is regulated by the Oklahoma Water Resources Board and has passed state inspections, it is in need of further risk assessment and management measures to ensure the safety of downstream communities and the environment. The dam's spillway is of the controlled type and features a single valve outlet gate, with a surface area of 2 acres and a normal storage capacity of 20 acre-feet. Its overall risk level is classified as very high, highlighting the importance of proactive risk mitigation strategies and emergency preparedness.
The dam's last inspection was conducted in 2009, and it is due for further assessments every 5 years. With its location in a high-risk area and the potential for flooding events, stakeholders and authorities must prioritize the implementation of emergency action plans, risk assessments, and maintenance measures to safeguard the dam's integrity and ensure the protection of downstream communities and water resources in the event of a catastrophic failure.

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.
