Lloyd Keller dam
Lloyd Keller
Lloyd Keller, also known as Greenberg Farms LLC, is a privately owned dam located in Marathon, Wisconsin, along the TR EAU PLEINE river. Built in 1966 by the USDA NRCS, this earth dam stands at a height of 10 feet and stretches 1020 feet in length. The dam serves primarily for recreational purposes and has a maximum storage capacity of 80 acre-feet.
Managed by the Wisconsin Department of Natural Resources (WIDNR), Lloyd Keller is regularly inspected, with the last assessment conducted in September 2010. Classified as a low hazard potential structure with a moderate risk assessment score of 3, the dam has not been rated for its current condition. While it has an uncontrolled spillway type, the dam poses no imminent threat. Despite its age, Lloyd Keller remains a vital part of the local water resource infrastructure, providing recreational opportunities in the area.
With its serene location in the heart of Wisconsin, Lloyd Keller offers a peaceful retreat for water resource and climate enthusiasts alike. As a well-maintained and regulated structure, it stands as a testament to responsible water management practices, ensuring the safety of surrounding communities and the preservation of the natural environment. Whether for fishing, boating, or simply enjoying the beauty of the TR EAU PLEINE river, Lloyd Keller continues to be a valuable asset for both locals and visitors to explore and appreciate.

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 Lloyd Keller
Where does the data for Lloyd Keller 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.
