Ellis Lake No. 2 Dam dam
Ellis Lake No. 2 Dam
Ellis Lake No. 2 Dam, located in Tiffin, Ohio, was completed in 1955 and serves as a vital water resource for recreation purposes in the area. This private-owned Earth dam stands at a height of 24.7 feet and has a storage capacity of 74.4 acre-feet. The dam spans 270 feet in length and covers a surface area of 6.6 acres, with a drainage area of 0.07 square miles.
Managed by the Department of Natural Resources in Ohio, Ellis Lake No. 2 Dam poses a significant hazard potential, although it was assessed to be in fair condition as of June 2018. The dam is subject to regular inspections, with the last one taking place in June 2018. With a normal storage capacity of 44.9 acre-feet, the dam plays a crucial role in managing water resources in the region and contributes to the overall environmental landscape, including the tributary to Porcupine Creek.
For water resource and climate enthusiasts, Ellis Lake No. 2 Dam stands out as a key infrastructure supporting recreational activities while also highlighting the importance of dam maintenance and inspection to ensure safety and water management efficiency. Its presence in Wyandot County, Ohio, reflects the intricate balance between human-made structures and natural ecosystems, underscoring the need for sustainable water resource management practices in the face of changing climate conditions.

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 Ellis Lake No. 2 Dam
Where does the data for Ellis Lake No. 2 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 Significant 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.
