North Hero 26 & 35 dam
North Hero 26 & 35
North Hero 26 & 35 in Minnesota is a rockfill dam with a primary purpose of flood risk reduction, located on Pell Creek-TR in Redwood County. The dam stands at a height of 21.3 feet and has a storage capacity of 114 acre-feet. It was last inspected in April 2019, with a low hazard potential and a condition assessment of "Not Rated". The dam is regulated by the Minnesota Department of Natural Resources, with state permitting, inspection, and enforcement in place to ensure its safety and functionality.
Despite its low hazard potential, North Hero 26 & 35 plays a crucial role in managing flood risks and protecting the surrounding area from potential inundation. The dam has not undergone any major modifications in recent years and has not been assigned a risk assessment or management plan. While the dam is currently in good condition, there is no Emergency Action Plan (EAP) in place, raising questions about the preparedness for any potential emergencies or disasters that may arise in the future.
Located in the city of Revere, North Hero 26 & 35 is owned by the local government and falls under the jurisdiction of the state of Minnesota. With Collin Peterson serving as the representative for the area in Congress, the dam provides essential flood protection for the community. Water resource and climate enthusiasts can appreciate the importance of infrastructure like North Hero 26 & 35 in safeguarding against the impacts of extreme weather events and ensuring the resilience of the local ecosystem.
Dam data reference
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 North Hero 26 & 35
Where does the data for North Hero 26 & 35 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.
