Republic Mine Tailings Pond Dams dam
Republic Mine Tailings Pond Dams
The Republic Mine Tailings Pond Dams in Marquette, Michigan, are a critical water resource infrastructure designed for tailings disposal. These private-owned dams were completed in 1960 and have a primary purpose of storing tailings material. Standing at a height of 91 feet and with a length of 22,300 feet, these earth-type dams have a capacity to hold 8,000 acre-feet of water.
Located in the city of Republic, these dams are regulated by the MICHIGAN DEGLE and undergo regular inspections to ensure their structural integrity. Despite being rated as having a low hazard potential, the risk assessment for these dams is classified as very high (1), emphasizing the need for robust risk management measures. The presence of a controlled spillway with a width of 74 feet adds to the safety features of these dams, which are situated near a tributary to the Michigamme River.
Enthusiasts of water resources and climate in the Michigan area would find the Republic Mine Tailings Pond Dams a significant subject of interest due to their historical significance, design features, and regulatory oversight. With a focus on tailings storage and water management, these dams play a crucial role in the local ecosystem and require ongoing monitoring and maintenance to mitigate potential risks and ensure their continued safe operation.

About Republic Mine Tailings Pond Dams
Where does the data for Republic Mine Tailings Pond Dams 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 below 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.

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.
