Plummer Basin Sw Clear Water Pond dam
Plummer Basin Sw Clear Water Pond
Plummer Basin Sw Clear Water Pond, located in Itasca County, Minnesota, is a privately owned dam designed by MAGNETATION for tailings storage. Constructed in 1947, this earth dam stands at a height of 40 feet and stretches 2100 feet in length, with a storage capacity of 120 acre-feet. The pond covers a surface area of 12 acres and drains an area of the same size, with a controlled spillway in place to manage water discharge.
Despite being classified as having a low hazard potential, this dam is under state regulation and inspection, ensuring its safety and compliance with required standards. The risk assessment for this structure is deemed very high, emphasizing the importance of ongoing monitoring and maintenance. While the condition assessment is currently not rated, regular inspections every 8 years help to mitigate any potential risks associated with the dam.
Water resource and climate enthusiasts can appreciate the significance of Plummer Basin Sw Clear Water Pond in managing tailings and water storage in the region. Its location on the Swan River-OS tributary and the efforts of the MNDNR EWR in overseeing its operations highlight the interconnectedness of water resources and environmental management in Minnesota. As part of the larger St. Paul District, this dam showcases the importance of infrastructure in balancing human needs with environmental conservation in a changing climate.

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 Plummer Basin Sw Clear Water Pond
Where does the data for Plummer Basin Sw Clear Water Pond 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.
