Detzman dam
Detzman
Detzman is a privately owned earth dam located in Lavalle, Wisconsin, along the Tr North Branch Honey Creek. Designed by USDA NRCS and completed in 1975, the dam stands at a height of 25 feet and has a length of 400 feet, providing flood risk reduction for the area. With a storage capacity of 68 acre-feet, the dam serves multiple purposes including fish and wildlife pond creation, flood risk reduction, and recreation.
Managed by the Natural Resources Conservation Service, Detzman has a low hazard potential and a moderate risk assessment rating. The dam features an uncontrolled spillway and outlet gates, with a maximum discharge of 160 cubic feet per second. Its surface area covers 4 acres, serving a drainage area of 0.48 square miles. While the dam's condition assessment is currently unavailable, it undergoes inspections every 10 years to ensure its integrity and safety.
With Congressman Mark Pocan representing the area, Detzman plays a crucial role in managing water resources and mitigating flood risks in Sauk County, Wisconsin. As a key structure in the St. Paul District, the dam contributes to the overall conservation efforts in the region. Despite its low hazard potential, Detzman remains a vital asset for the community, highlighting the importance of proper dam maintenance and risk management 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 Detzman
Where does the data for Detzman 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.
