About this dam

Sunset Lake Dam

Sunset Lake Dam, also known as Lee Paper Company Dam, is a privately owned structure located in Vicksburg, Michigan, along Gourdneck Creek. Built in 1850, this Earth-type dam stands at a height of 11.06 feet and serves primarily for recreational purposes, with a normal storage capacity of 320 acre-feet. Its controlled spillway, with a width of 10 feet, helps manage a maximum discharge of 729 cubic feet per second. The dam's hazard potential is categorized as high, yet its condition assessment as of July 2020 was deemed satisfactory.

Managed by the Michigan Department of Great Lakes, Energy, and Environment (DEGLE), Sunset Lake Dam undergoes regular inspections and enforcement to ensure its operational safety and compliance with state regulations. The dam's risk assessment is classified as very high, prompting the need for effective risk management measures. Despite its age, Sunset Lake Dam continues to provide a recreational oasis for the local community, offering a scenic 97-acre surface area for outdoor activities such as fishing, boating, and wildlife observation. As climate change impacts water resources and infrastructure, the resilience and maintenance of dams like Sunset Lake Dam are increasingly vital in safeguarding both the environment and public safety.

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.

FAQ

About Sunset Lake Dam

Where does the data for Sunset Lake 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 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.
