Seven Lakes Addition Dam dam
Seven Lakes Addition Dam
Seven Lakes Addition Dam, also known as Little Seven Lake Dam, is a state-owned structure located in Flint, Michigan. Completed in 1970, this earth dam serves primarily for recreational purposes, showcasing a height of 25.5 feet and a hydraulic height of 22.3 feet. It impounds the waters of Swartz Creek, offering a serene and picturesque setting for outdoor enthusiasts and nature lovers.
With a storage capacity of 335 acre-feet and a drainage area of 0.26 square miles, Seven Lakes Addition Dam features an uncontrolled spillway with a width of 8 feet. The dam has been deemed to have a low hazard potential and is in a satisfactory condition, as per the latest inspection conducted in October 2020. Despite its moderate risk assessment score of 3, the dam remains a popular destination for locals and visitors alike, contributing to the beauty and recreational opportunities in Oakland County, Michigan.
Managed by the Michigan Department of Environment, Great Lakes, and Energy (DEGLE), Seven Lakes Addition Dam stands as a vital component of the local water resource infrastructure. With its historical significance and ongoing role in providing recreation and water storage, the dam serves as a testament to the importance of sustainable water management practices in the face of changing climate patterns and environmental challenges.

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 Seven Lakes Addition Dam
Where does the data for Seven Lakes Addition 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 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.
