Werrmann Lake Dam dam
Werrmann Lake Dam
Located in South Lebanon, Ohio, Werrmann Lake Dam stands as a vital structure regulating water flow in the tributary to Halls Creek. Managed by a private entity, this earth dam primarily serves recreational purposes, offering a serene retreat for water resource and climate enthusiasts. With a height of 25.9 feet and a storage capacity of 33.7 acre-feet, this dam covers a surface area of 3.7 acres and plays a crucial role in maintaining the ecological balance of the region.
Despite its essential functions, Werrmann Lake Dam currently faces challenges with a poor condition assessment as of 2019. The dam's hazard potential is classified as low, but its structural integrity requires attention to ensure long-term reliability. Furthermore, the dam lacks an Emergency Action Plan (EAP) and updated inundation maps, raising concerns about readiness in case of emergencies. With the Department of Natural Resources overseeing regulation, continued inspections and maintenance are crucial to safeguard this important water resource infrastructure.
As efforts are made to address the dam's structural concerns, stakeholders are urged to prioritize regular inspections and necessary repair work to enhance its resilience and effectiveness. By ensuring compliance with state regulations and investing in risk management measures, the Werrmann Lake Dam can continue to provide valuable recreational opportunities while contributing to the sustainable management of water resources in Warren County, Ohio.

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 Werrmann Lake Dam
Where does the data for Werrmann 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.
