Summary
Completed in 1970, this Earth-type dam stands at a height of 25 feet and has a length of 3320 feet. Its primary purpose is classified as "Other," with a low hazard potential and a very high risk assessment rating of 1. The dam is regulated by the Oklahoma Water Resources Board (OWRB) and meets state permitting, inspection, and enforcement requirements.
This dam, situated on the TR-Wolf Creek river/stream, has a maximum storage capacity of 60 acre-feet and a normal storage capacity of 20 acre-feet. It features a controlled spillway with a width of 1 foot and is equipped with a valve outlet gate. Despite its age, the dam has not been rated for its condition assessment, and its last inspection was conducted in August 2011. The risk management measures and emergency action plan for this structure are currently not available, highlighting potential areas for improvement in safeguarding against any unforeseen emergencies or disasters.
Overall, Oknoname 111059 serves as a crucial infrastructure for water resource management in the area, contributing to flood control and water storage. As a privately owned dam, it is subject to state regulations and oversight to ensure its safe operation and maintenance. The data provided offers insight into the structure's design, dimensions, and regulatory compliance, shedding light on its role in supporting the local ecosystem and communities reliant on its water resources.

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.
