Addison Mill Pond Dam dam
Addison Mill Pond Dam
Addison Mill Pond Dam, located in Addison, Michigan, is a local government-owned structure that serves the primary purpose of recreation. Built in 1837, this Earth-type dam stands at a height of 24.5 feet and has a hydraulic height of 25 feet, with a length of 225 feet. The dam's reservoir has a normal storage capacity of 96 acre-feet and covers a surface area of 50 acres, with a drainage area of 16.2 square miles.
The dam poses a high hazard potential and has been assessed to be in fair condition as of the last inspection in July 2019. Despite its age, the dam continues to provide recreational opportunities and contributes to the overall water resource management in the area. With its location on Bean Creek and its historical significance dating back over a century, Addison Mill Pond Dam remains a notable feature for water resource and climate enthusiasts interested in the region's infrastructure and environmental impact.
Although the dam is regulated by the Michigan Department of Environment, Great Lakes, and Energy, ongoing inspections and enforcement ensure its safety and compliance with state regulations. The risk assessment for the dam is categorized as moderate, indicating a need for continued monitoring and potential risk management measures to maintain its structural integrity and safeguard against any potential hazards. Overall, Addison Mill Pond Dam stands as a historic landmark that plays a vital role in both water resource management and recreational activities in Lenawee County, Michigan.

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 Addison Mill Pond Dam
Where does the data for Addison Mill Pond 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 High 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.
