Miller Bros. dam
Miller Bros.
Miller Bros. is a privately owned earth dam located along the TR-Moreau River in Perkins, South Dakota. Constructed in 1958 by the Natural Resources Conservation Service, this dam stands at a height of 20 feet and has a length of 320 feet, with a storage capacity of 62 acre-feet. While it has a low hazard potential and is currently rated as "Not Rated" in terms of condition assessment, the dam is regulated by the South Dakota Department of Environment and Natural Resources, with state permitting, inspection, and enforcement procedures in place.
The Miller Bros. dam plays a crucial role in water resource management in the region, serving as a vital infrastructure for flood control, water supply, and irrigation purposes. Situated within the St. Paul District of the US Army Corps of Engineers, the dam also contributes to the overall environmental health and resilience of the area. Despite its age, the dam continues to provide valuable services to the community and remains an essential component of the local water infrastructure.
As climate change and water scarcity issues continue to pose challenges to water resource management, the maintenance and upkeep of dams like Miller Bros. becomes increasingly important. With proper monitoring and adherence to regulatory guidelines, this dam can continue to fulfill its role in safeguarding the local ecosystem and ensuring sustainable water supply for the future.

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 Miller Bros.
Where does the data for Miller Bros. 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.
