Amiret 33 & Monroe 4 dam
Amiret 33 & Monroe 4
Amiret 33 & Monroe 4 is a dam located in Lyon County, Minnesota, along the Cottonwood River. Owned by the local government, this dam stands at a height of 15 feet and has a length of 380 feet. The dam has a storage capacity of 121 acre-feet and serves as a roadway retention structure. It is regulated by the Minnesota Department of Natural Resources and undergoes regular inspections to ensure its safety and compliance with state regulations.
The structure is classified as a Buttress dam with an unlisted/unknown foundation type. Despite its low hazard potential, the dam's condition assessment is currently listed as "Not Rated" as of the last inspection in April 2019. Emergency action plans and risk assessment measures for the dam have not been updated or prepared, highlighting the need for continued monitoring and evaluation of the structure's safety and functionality. With its location in a critical watershed area, the Amiret 33 & Monroe 4 dam plays a crucial role in water resource management and flood control efforts in the region.
Water resource and climate enthusiasts can appreciate the significance of the Amiret 33 & Monroe 4 dam in Lyon County, Minnesota. As a key infrastructure owned and regulated by the local government, this structure helps to manage water flow along the Cottonwood River and provides important retention functions for surrounding roadways. With a storage capacity of 121 acre-feet, the dam plays a vital role in flood control and water resource management in the area. Continued monitoring and inspection of the dam will be essential to ensure its safety and effectiveness in the face of changing climate patterns and water resource demands.

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 Amiret 33 & Monroe 4
Where does the data for Amiret 33 & Monroe 4 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.
