Summary
Constructed in 1960, this earth dam stands at a height of 20 feet and spans a length of 480 feet, with a maximum storage capacity of 50 acre-feet. The dam is regulated by the Oklahoma Water Resources Board and is subject to regular inspections and enforcement measures to ensure its safety and compliance with state regulations.
Situated on Bourbinais Creek, Oknoname 027003 serves a primary purpose classified as "Other", with a low hazard potential and a very high risk assessment rating. The dam features a controlled spillway and a single valve outlet gate. Although it has not been officially rated for its condition, the dam undergoes inspections every five years, with the last inspection conducted in August 2010. Despite its low hazard potential, the risk assessment for this dam remains very high, indicating the need for continued monitoring and potential risk management measures in the future.
In the event of an emergency, the dam does not have an Emergency Action Plan (EAP) prepared, and there is no designated emergency contact information available. Overall, Oknoname 027003 presents an intriguing case study for water resource and climate enthusiasts, highlighting the importance of proper dam maintenance, risk assessment, and emergency preparedness in ensuring the safety and resilience of critical infrastructure in the face of changing environmental conditions.

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.
