Richard Jahnke dam
Richard Jahnke
Richard Jahnke is a private earth dam located in Pepin, Wisconsin, along the Tr Chippewa river. Built in 1974 by the USDA NRCS, this dam stands 31 feet tall and spans 600 feet, with a storage capacity of 20 acre-feet. Its primary purpose is flood risk reduction, serving as a vital infrastructure in safeguarding the surrounding area from potential inundation during high water events.
Managed and funded by the Natural Resources Conservation Service, Richard Jahnke has a low hazard potential and a moderate risk assessment rating. Despite limited information on its condition assessment, this dam plays a crucial role in mitigating flood risks in the region. With its uncontrolled spillway and outlet gates, Richard Jahnke serves as a reliable structure in ensuring the safety and protection of the local community from potential flooding events.
For water resource and climate enthusiasts, Richard Jahnke represents a key component in the ecosystem, showcasing the importance of infrastructure in managing and controlling water flow to mitigate flood risks. Its construction and design by the USDA NRCS highlight the collaboration between government agencies and private entities to safeguard communities from natural disasters. As a low-hazard dam with a moderate risk assessment, Richard Jahnke stands as a testament to effective flood risk reduction measures in the region.

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 Richard Jahnke
Where does the data for Richard Jahnke 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.
