Summary
Built in 1965, this dam stands at a height of 21 feet and has a capacity to store up to 95.87 acre-feet of water. It serves as a vital component in regulating the flow of the tributary to Wildcat Creek, with a maximum discharge capacity of 177.3 cubic feet per second.
Managed by the Oklahoma Water Resources Board, Williams Dam is classified as a low hazard potential structure with a moderate risk assessment rating. Although its condition has not been officially assessed, the dam is regularly inspected every 5 years to ensure its structural integrity and safety. Despite its modest size, this dam plays a significant role in water conservation efforts in the area, with a normal storage capacity of 67.75 acre-feet and a surface area of 6.25 acres.
With a spillway width of 25 feet and uncontrolled spillway type, Williams Dam is designed to manage excess water flow during heavy rainfall events. While it does not have any associated locks or outlet gates, the dam serves its primary purpose effectively and contributes to the overall water resource management infrastructure in Stephens County, Oklahoma. As climate change continues to impact water resources, structures like Williams Dam play a critical role in mitigating the effects of extreme weather events and ensuring a sustainable water supply for the community.

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.
