Carlson Dam dam
Carlson Dam
Carlson Dam, located in Foster City, Michigan, was completed in 1963 by the USDA NRCS and serves multiple purposes including fire protection, stock, and small fish pond. The earth dam stands at 10 feet high and stretches 300 feet in length, with a storage capacity of 60 acre-feet. The dam, situated on a tributary to Quarry Creek, has a low hazard potential and is currently rated as "Not Rated" in terms of condition assessment.
Despite being privately owned, Carlson Dam falls under state jurisdiction with no regulatory agency overseeing its operations. The dam features an uncontrolled spillway and has not undergone any modifications since its construction. With a moderate risk assessment rating of 3, the dam has a designated inspection frequency of 5 years, with the last inspection recorded on January 1, 1901. Emergency action plans and inundation maps have not been prepared, raising concerns about the dam's readiness for potential emergencies.
Overall, Carlson Dam stands as a crucial water resource infrastructure contributing to the local ecosystem and providing essential services to the community. As a focal point for water resource and climate enthusiasts, the dam's unique design and historical significance highlight the importance of maintaining and monitoring such structures for the safety and well-being of surrounding areas.

About Carlson Dam
Where does the data for Carlson 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 below 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.

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.
