Holman Clear Water Pond dam
Holman Clear Water Pond
Holman Clear Water Pond, located in Itasca, Minnesota, is a private water resource built on an old railroad line for 20th-century mining trains. Managed by MAGNETATION, this pond serves as a tailings storage facility with a dam height of 49 feet and a length of 1100 feet. Completed in 2012, it has a storage capacity of 360 acre-feet and covers a surface area of 35 acres.
The pond is regulated by the Minnesota Department of Natural Resources and undergoes regular inspections, with a low hazard potential and no rated condition assessment. Despite being privately owned, it is subject to state jurisdiction and permitting requirements. Holman Clear Water Pond is situated near the Swan River and is part of the St. Paul District, with Congressman Pete Stauber representing the area. Its purpose primarily revolves around tailings storage, contributing to the local water management and resource conservation efforts.
With an emphasis on safety and compliance, this water management structure plays a crucial role in environmental protection and sustainable resource utilization in the region. As a key component of the local water infrastructure, Holman Clear Water Pond stands as a testament to responsible resource management practices and the importance of regulatory oversight in safeguarding our precious water resources for future generations.
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 Holman Clear Water Pond
Where does the data for Holman 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.
