Ann Twp 6 dam
Ann Twp 6
Located in Revere, Minnesota, Ann Twp 6 is a rockfill dam along Pell Creek, designed for flood risk reduction. This local government-owned structure is regulated by the Minnesota Department of Natural Resources and is equipped with state permitting, inspection, and enforcement measures in place. With a dam height of 26 feet and a storage capacity of 425 acre-feet, Ann Twp 6 serves as a vital component in managing the water resources and mitigating flood risks in the Cottonwood County area.
The dam, with a length of 1000 feet, plays a significant role in safeguarding the surrounding area from potential hazards. Although the condition assessment is currently not rated, the structure undergoes inspections every four years to ensure its integrity and functionality. With a hazard potential classified as "significant," Ann Twp 6 remains a crucial asset in the region's water resource management efforts, highlighting the importance of sustainable infrastructure in combating the impacts of climate change and extreme weather events.
As water resource and climate enthusiasts continue to advocate for resilient infrastructure and effective risk mitigation strategies, the presence of structures like Ann Twp 6 underscores the ongoing efforts to protect communities and ecosystems from the adverse effects of flooding. With its strategic location and purposeful design, this rockfill dam stands as a testament to the collaborative initiatives between local governments, regulatory agencies, and environmental stakeholders in safeguarding water resources and enhancing climate resilience 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 Ann Twp 6
Where does the data for Ann Twp 6 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 Significant 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.
