Dexter 30 dam
Dexter 30
Dexter 30, located in Mower County, Minnesota, is a key piece of infrastructure owned by the local government and regulated by the Minnesota Department of Natural Resources. Completed in 2020, this dam serves the primary purpose of flood risk reduction in the region, with a storage capacity of 224 acre-feet and a maximum height of 17 feet. The dam is equipped with vertical lift outlet gates and has a low hazard potential, with a satisfactory condition assessment as of January 2020.
Even though Dexter 30 has not been associated with any other structures and does not have a designated dam type or core type, it plays a crucial role in managing flood risk in the area. With a regular inspection frequency of 8 years and a solid emergency action plan in place, this dam ensures the safety of the surrounding community in case of any unforeseen events. The dam's design and operation comply with state permitting and regulatory requirements, contributing to the overall resilience of the local water resource infrastructure.
In conclusion, Dexter 30 serves as a vital component in the flood risk reduction efforts of Mower County, Minnesota. With its low hazard potential, satisfactory condition assessment, and efficient operation, this dam exemplifies the importance of proactive water resource management in mitigating the impact of extreme weather events and safeguarding the community against potential floods. As climate change continues to pose challenges to water resource management, Dexter 30 stands as a testament to the resilience and adaptability of infrastructure in the face of evolving environmental conditions.
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 Dexter 30
Where does the data for Dexter 30 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.
