Summary
Standing at a height of 22 feet with a hydraulic height of 18 feet, this dam has a storage capacity of 145 acre-feet and a surface area of 13 acres. It is regulated by the Oklahoma Water Resources Board and is subject to state inspections and enforcement, ensuring its structural integrity and safety.
The dam, situated on the TR-ISLAND BAYOU river/stream, has a controlled spillway with a width of 1 foot and is equipped with a single valve outlet gate. Despite being classified as having low hazard potential, it has a very high risk assessment due to its condition being not rated, indicating a need for further evaluation and monitoring. The last inspection was conducted in 1999, with an inspection frequency of every 5 years, highlighting the importance of regular assessments to prevent potential risks and ensure public safety.
In the event of an emergency, the dam's Emergency Action Plan (EAP) status is unclear, with no information available on its preparation or last revision date. However, the dam is not owned or funded by any federal agency, suggesting that emergency response and management would likely fall under private ownership. As water resource and climate enthusiasts, monitoring and assessing the condition of Oknoname 013013 is crucial to understanding its impact on the surrounding ecosystem and ensuring its long-term sustainability 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.
