Ninefeldt Pool dam
Ninefeldt Pool
Ninefeldt Pool, located in Carlton County, Minnesota, is a privately-owned earth dam constructed in 1969 by the USDA NRCS. This dam, situated on the Moose Horn River West Branch, serves a primary purpose that falls under the category of "Other." With a height of 7 feet and a length of 430 feet, Ninefeldt Pool has a storage capacity of 132 acre-feet and a drainage area of 0.4 square miles.
Managed by the Minnesota Department of Natural Resources, Ninefeldt Pool is regulated, permitted, inspected, and enforced by state agencies to ensure its structural integrity and safety. The dam has a low hazard potential and is currently in satisfactory condition as assessed in September 2017. While the spillway type is uncontrolled, the risk assessment for Ninefeldt Pool is considered moderate. Overall, this dam plays a crucial role in water resource management in the area, contributing to flood control and water storage for various purposes.
With its strategic location and purposeful design, Ninefeldt Pool stands as a testament to effective water management practices in Minnesota. As a key structure in the region, it not only provides essential water storage but also underscores the importance of proper regulation and maintenance in safeguarding water resources and mitigating potential risks. For water resource and climate enthusiasts, Ninefeldt Pool serves as a fascinating example of how human intervention can positively impact the natural environment while ensuring the safety and well-being of surrounding communities.
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 Ninefeldt Pool
Where does the data for Ninefeldt Pool 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.
