Thor Lake Dam dam
Thor Lake Dam
Thor Lake Dam, located in Muttonville, Ohio, is a private recreational dam built in 1970 by American Realty Service Corp. The dam stands at a height of 39 feet and spans 720 feet in length, with a storage capacity of 170 acre-feet. Situated on a tributary to Paint Creek, the dam serves as a popular spot for outdoor enthusiasts seeking recreational activities such as boating and fishing.
Managed by the Department of Natural Resources in Ohio, Thor Lake Dam has been inspected regularly, with a hazard potential rated as low and a fair condition assessment. The dam's emergency action plan is up-to-date, ensuring that proper measures are in place in case of any unforeseen events. Despite its modest size, the dam plays a vital role in providing water-based recreational opportunities for the local community while adhering to state regulatory standards.
With its picturesque setting and well-maintained structure, Thor Lake Dam serves as a testament to the importance of sustainable water resource management for both recreational and environmental purposes. As climate change continues to impact water resources, dams like Thor Lake play a crucial role in maintaining the balance between human enjoyment and ecological preservation. As enthusiasts of water resources and climate, the Thor Lake Dam is a prime example of how careful planning and regulation can ensure the safety and sustainability of our water infrastructure for generations to come.

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 Thor Lake Dam
Where does the data for Thor 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.
