Nordine Dam dam
Nordine Dam
Nordine Dam, also known as Nordine Pond Dam, is a privately owned structure located in Ontonagon, Michigan, along the Walton Creek. Built in 1970, this earth dam stands at a height of 9 feet and stretches 290 feet in length, with a storage capacity of 65 acre-feet. The primary purpose of Nordine Dam is for recreation, providing a surface area of 26 acres and a maximum discharge capacity of 100 cubic feet per second.
Despite its low hazard potential, Nordine Dam is regulated by the Michigan Department of Environment, Great Lakes, and Energy (DEGLE), with regular inspections conducted every 5 years. The dam features an uncontrolled spillway with a width of 17 feet, serving as a safety measure in case of overflow. While the condition of Nordine Dam is currently not rated, its risk assessment is categorized as moderate, indicating a level 3 risk.
Enthusiasts of water resources and climate in the Houghton County area may find Nordine Dam to be an interesting site for recreational activities and potential environmental impact studies. With its unique design and historical significance dating back to the early 1970s, the dam offers a glimpse into the region's water management practices and serves as a focal point for understanding the interaction between human-made structures and natural ecosystems in Michigan's landscape.

About Nordine Dam
Where does the data for Nordine Dam 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.
