Summary
Completed in 1973, the dam stands at a height of 22 feet and spans 450 feet in length. With a storage capacity of 66 acre-feet and a surface area of 30 acres, the dam serves as a popular spot for outdoor activities in the Wayne County area.
Despite its low hazard potential and moderate risk assessment rating, Williams Lake Dam has not been state-regulated or inspected, raising concerns among water resource and climate enthusiasts. The dam features an uncontrolled spillway with a width of 14 feet, and lacks outlet gates for drainage control. Although designated as a low-risk structure, the absence of recent inspections and maintenance assessments leaves the dam's condition and safety uncertain.
As a key recreational site in the St. Louis District, Williams Lake Dam's management and maintenance protocols warrant closer attention to ensure the safety of both visitors and the surrounding environment. With its potential impact on Bear Creek and the local ecosystem, proactive measures and regular inspections are crucial to mitigate any unforeseen risks and uphold the dam's integrity for future generations of water resource and climate enthusiasts.

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.
