Summary
Built in 1970, this earth dam boasts a height of 24 feet and a length of 310 feet, providing a storage capacity of 72 acre-feet. With a controlled spillway and a valve outlet gate, Wilson C has been deemed to have a significant hazard potential but is currently in satisfactory condition as of the last inspection in December 2020.
Managed by the Oklahoma Water Resources Board, Wilson C serves a primary purpose of "Other" and is vital for water resource management in the area. Despite its age, the dam continues to be regulated, inspected, and enforced by state agencies to ensure its safety and functionality. With a very high risk assessment rating, the dam poses challenges that necessitate careful monitoring and risk management measures to mitigate potential hazards and ensure the safety of surrounding communities.
As water resource and climate enthusiasts, the intricate details of Wilson C's construction, design, and operational aspects offer valuable insights into the intersection of human infrastructure and natural ecosystems. From the dam's stone core and soil foundation to its controlled spillway and valve outlet gate, each component plays a crucial role in maintaining the dam's integrity and functionality. With a significant hazard potential and a very high risk assessment rating, Wilson C stands as a testament to the delicate balance between harnessing water resources for human needs and mitigating the risks associated with large-scale infrastructure projects in a changing climate.

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.
