Summary
Situated on the TR-NORTH FORK RED RIVER, this dam stands at a height of 17 feet with a hydraulic height of 12 feet, containing a storage capacity of 80 acre-feet and covering a surface area of 18 acres. With a controlled spillway and one outlet gate, the dam has a low hazard potential but a very high risk assessment rating of 1.
Despite being privately owned, Wilson 115 is regulated by the Oklahoma Water Resources Board (OWRB) and has undergone state permitting, inspection, and enforcement procedures. The dam has not been modified in recent years and is currently in a condition that is not rated. Emergency action plans (EAP) and risk management measures for Wilson 115 are not readily available, indicating a potential area for improvement in terms of preparedness and response to any unforeseen events. Overall, Wilson 115 serves as a vital resource for irrigation in the region, highlighting the importance of proper maintenance and monitoring to ensure its continued functionality and safety.

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.
