Summary
Built in 1940, this structure stands at a height of 21 feet and has a length of 700 feet, with a storage capacity of 320 acre-feet. The dam is regulated by the Oklahoma Water Resources Board and is subject to state jurisdiction, permitting, inspection, and enforcement.
Situated on the TR-Tiger Creek, this dam has a controlled spillway and one outlet valve. Despite being classified as having a low hazard potential, the risk assessment for Oknoname 111013 is very high (1). The last inspection of the dam took place in August 2011, with a scheduled inspection frequency of every 5 years. The condition assessment currently remains unrated, and there are no Emergency Action Plans (EAP) in place.
Overall, Oknoname 111013 serves as a critical water resource management structure in the region, providing essential storage and flood control capabilities. However, the high risk assessment highlights the need for continued monitoring and potential risk management measures to ensure the safety and integrity of the dam in the face of changing climate conditions and increased water management challenges.

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.
