Chequamegon Waters dam
Chequamegon Waters
Chequamegon Waters, also known as Miller Dam, is a gravity dam located in GILMAN, Wisconsin, within Taylor County. Completed in 1967, this dam serves a primary purpose of recreation, offering visitors a tranquil spot for outdoor activities. With a height of 22 feet and a length of 800 feet, it impounds the YELLOW river, creating a surface area of 2714 acres and a storage capacity of 45,000 acre-feet.
Managed by the Wisconsin Department of Natural Resources, this dam is subject to state regulation, permitting, inspection, and enforcement. Despite its satisfactory condition assessment and high hazard potential, it is equipped with a controlled spillway and has a very high risk assessment rating. The dam has a drainage area of 125 square miles and a maximum discharge capacity of 9,910 cubic feet per second, making it a crucial feature in the region's water resource management.
With its picturesque surroundings and important role in water regulation, Chequamegon Waters is a must-visit destination for water resource and climate enthusiasts. Its rich history, recreational opportunities, and environmental significance make it a valuable piece of Wisconsin's landscape, contributing to both the local community and the state's overall water management efforts.
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 Chequamegon Waters
Where does the data for Chequamegon Waters 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.
