Hatlevig-Boyum Group dam
Hatlevig-Boyum Group
The Hatlevig-Boyum Group, also known as the Hatlevig-Boyum Dam, is a private-owned structure located in Rushford, Minnesota, on the Pine Creek-TR river. Built in 1976 by the USDA NRCS, this earth dam stands at a height of 27 feet and has a length of 43 feet. Its primary purpose is flood risk reduction, with a storage capacity of 40 acre-feet and a drainage area of 0.8 square miles.
Managed by the MNDNR EWR, the Hatlevig-Boyum Group is regulated, permitted, inspected, and enforced by the state of Minnesota. Its hazard potential is rated as low, with a satisfactory condition assessment conducted in April 2016. The dam is equipped with uncontrolled spillways and outlet gates, with a maximum discharge capacity of 775 cubic feet per second. Despite its moderate risk rating, the structure meets regulatory guidelines and has not been significantly modified since its completion.
For water resource and climate enthusiasts, the Hatlevig-Boyum Group serves as an essential flood risk reduction infrastructure in Fillmore County, Minnesota. Its presence highlights the importance of maintaining and monitoring dams to ensure public safety and the protection of surrounding communities from potential inundation. As part of the broader water management system, this dam plays a crucial role in mitigating the impact of extreme weather events and safeguarding the local ecosystem.

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 Hatlevig-Boyum Group
Where does the data for Hatlevig-Boyum 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.
