Summary
Situated on a tributary to Stony Creek, this earth dam stands at a height of 26 feet, with a length of 330 feet and a storage capacity of 29 acre-feet. Despite its low hazard potential, the dam's condition assessment is rated as poor, indicating a need for maintenance and repairs.
Managed by the Department of Natural Resources in Ohio, Williams Lake Dam is subject to state regulations, permitting, inspection, and enforcement. The dam's last inspection in November 2019 revealed its poor condition, highlighting the importance of ongoing monitoring and maintenance to ensure its structural integrity and safety. With a drainage area of 0.05 square miles and a maximum discharge capacity of 771 cubic feet per second, the dam plays a crucial role in managing water resources in the region.
For water resource and climate enthusiasts, Williams Lake Dam presents an intriguing case study of a privately owned recreational structure with significant implications for local water management. As efforts continue to assess and address the dam's deteriorating condition, stakeholders and authorities are working to mitigate potential risks and safeguard the surrounding community and environment. The dam's location, design, and storage capacity make it a vital component of the region's water infrastructure, underscoring the importance of ongoing maintenance and regulatory oversight to ensure its long-term 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.
