Long-On-Deerskin dam
Long-On-Deerskin
Long-On-Deerskin is a beautiful hydroelectric dam located in Vilas, Wisconsin, along the Deerskin River. Built in 1908, this gravity dam stands at 9.5 feet tall and spans 83 feet in length, with a storage capacity of 60,859 acre-feet. The dam serves multiple purposes, including flood risk reduction and hydroelectric power generation, making it a crucial infrastructure for the region.
Managed by the Federal Energy Regulatory Commission, Long-On-Deerskin has a low hazard potential but is classified as having a very high risk due to its age and condition assessment not being available. The dam features a controlled spillway and a Tainter (radial) outlet gate for water discharge. Despite not being under state jurisdiction, the dam's inspection frequency is set at every 3 years to ensure its safety and integrity. With its historical significance and environmental impact, Long-On-Deerskin stands as a testament to the importance of water resource management and climate resilience in Wisconsin.
Overall, Long-On-Deerskin represents a blend of history, engineering, and environmental stewardship. As a public utility structure, it plays a vital role in the local community by providing clean energy and mitigating flood risks. With its picturesque location in Eagle River and its contributions to the region's water infrastructure, Long-On-Deerskin serves as a reminder of the interconnectedness between water resources and climate considerations, highlighting the need for sustainable practices in managing our natural resources.
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 Long-On-Deerskin
Where does the data for Long-On-Deerskin 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.
