Legend Lake Number Three dam
Legend Lake Number Three
Legend Lake Number Three, located in Menominee, Wisconsin, is a privately owned dam constructed in 1971 primarily for recreational purposes. This gravity-type dam, standing at 22 feet tall with a hydraulic height of 15 feet, spans a length of 1200 feet and has a storage capacity of 20,000 acre-feet. The reservoir covers a surface area of 1304 acres and is fed by Linzy Creek, with a drainage area of 21.8 square miles.
Despite its satisfactory condition assessment as of October 2020, Legend Lake Number Three has a high hazard potential, with a very high risk assessment rating. The dam is regulated by the Wisconsin Department of Natural Resources, which conducts regular inspections and enforces safety measures. The last inspection was carried out in July 2019, with a frequency of every two years. In the event of an emergency, the dam's emergency action plan is in place, although its last revision dates back to 2014.
Water resource and climate enthusiasts will be intrigued by the engineering and environmental aspects of Legend Lake Number Three. Its controlled spillway, high hazard potential, and risk assessment rating provide insight into the complex management and regulation of water resources in Wisconsin. The dam's location within a recreational area adds an additional layer of significance, highlighting the intersection between human recreation and the natural environment.
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.
Plan around the weather

About Legend Lake Number Three
Where does the data for Legend Lake Number Three 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 High 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.
