Williams Lake Dam dam
Williams Lake Dam
Williams Lake Dam, located in Tremont City, Ohio, is a privately owned structure designed by Charles Williams and completed in 1964 for the primary purpose of recreation. 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
- Satisfactory
- No 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.
- 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.
- 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.
Hazard Potential Classification
- High
- Dams 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, environmental 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.

About Williams Lake Dam
Where does the data for Williams Lake Dam come from?
Structural and regulatory data come from the U.S. Army Corps of Engineers' National Inventory of Dams (NID). Weather forecast comes from NOAA / yr.no -- the same feed Snoflo's iOS app uses.
How often is the report updated?
NID structural data refreshes annually as the Corps publishes updated assessments. The weather forecast refreshes throughout the day.
What does the Low hazard rating mean?
The Corps of Engineers' hazard potential classification grades probable consequences if the dam fails: High = probable loss of human life; Significant = no probable loss of human life but possible economic loss / environmental damage; Low = no probable loss of human life, only minor economic / environmental losses. See the Dam Data Reference card above for the full definitions.
What's "% of normal"?
The current storage value compared to the historical average storage on this calendar day. 100% = right on average; values above 100% mean above-normal storage (wet year); values below mean below-normal (dry year or drought).
Can I get alerts when storage crosses a threshold?
Yes -- alerts are managed in the Snoflo iOS app. Favorite this dam, set a threshold, and you'll get a push the moment conditions cross.
