Hg Armbruster Group dam
Hg Armbruster Group
The Hg Armbruster Group is a privately owned dam located in Pierce, Wisconsin, designed by the USDA NRCS in 1962. This earth dam, with a height of 29 feet and a length of 308 feet, serves multiple purposes including fire protection and providing water for stock or small fish ponds. It is regulated by the Wisconsin Department of Natural Resources and has state permitting, inspection, and enforcement in place.
Situated on a tributary to the Trimbelle River, the Hg Armbruster Group dam has a low hazard potential and is currently rated as "Not Rated" in terms of its condition assessment. This dam has a storage capacity of 47 acre-feet, with a normal storage level of 9 acre-feet and a maximum discharge of 245 cubic feet per second. While the risk assessment for this dam is considered very high, it has not yet been assigned a Dam Safety Action Classification (DSAC) date.
Overall, the Hg Armbruster Group dam is an essential structure for fire protection and water resource management in the area. With its controlled spillway and state-regulated status, this dam plays a crucial role in ensuring water availability for various purposes while adhering to safety and regulatory standards. For water resource and climate enthusiasts, this dam serves as a significant example of responsible water infrastructure management in Wisconsin.

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 Hg Armbruster Group
Where does the data for Hg Armbruster Group 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.
