Dundee dam
Dundee
Dundee, also known as Long Lake, is a picturesque water resource located in Fond du Lac, Wisconsin. Managed by the local government, this dam was completed in 1857 with a primary purpose of recreation. The earth dam stands at 8 feet tall and spans 280 feet in length, creating a surface area of 427 acres and a normal storage capacity of 2000 acre-feet.
With a drainage area of 24.5 square miles and a max discharge of 500 cubic feet per second, Dundee poses a significant hazard potential but is currently assessed to be in fair condition. The dam is regulated by the Wisconsin Department of Natural Resources and undergoes regular inspections, with the last assessment conducted in May 2020. The risk assessment for Dundee is moderate, and emergency preparedness plans are in place to ensure public safety in the event of an emergency.
For water resource and climate enthusiasts, Dundee offers a fascinating opportunity to explore the intersection of human infrastructure and natural landscapes. With its rich history dating back over a century, this recreational dam on the East Branch Milwaukee River serves as a vital water source while providing a serene backdrop for outdoor activities. As climate change continues to impact water resources, understanding the management and maintenance of structures like Dundee becomes increasingly essential for sustainable water management practices.

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 Dundee
Where does the data for Dundee 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.
