Dingman Marsh Flooding Dam dam
Dingman Marsh Flooding Dam
The Dingman Marsh Flooding Dam, located in Mackinaw, Michigan, is a state-regulated structure designed for recreational purposes along Mill Creek. Completed in 1959, this earth dam stands at a height of 10.6 feet with a hydraulic height of 7.5 feet, providing a storage capacity of 5350 acre-feet and a normal storage of 2240 acre-feet. The dam spans 1100 feet in length and has a surface area of 700 acres, serving as a popular spot for outdoor activities in the Cheboygan County area.
Despite its low hazard potential and satisfactory condition assessment as of July 2016, the Dingman Marsh Flooding Dam is subject to regular inspections and enforcement by the Michigan DEGLE. With a moderate risk assessment rating of 3, measures have been put in place to ensure the safety and reliability of this structure for the surrounding community. As an integral part of the local ecosystem and recreational landscape, the dam plays a key role in water resource management and flood control along the Mill Creek watershed.
As climate change continues to impact water resources and infrastructure, the Dingman Marsh Flooding Dam stands as a testament to the importance of sustainable dam operations and maintenance. With its uncontrolled spillway, the dam serves as a vital component of the Detroit District's water management system, ensuring proper discharge and flood protection for the area. As water resource and climate enthusiasts, it is crucial to monitor and support the ongoing efforts to maintain and enhance the resilience of structures like the Dingman Marsh Flooding Dam in the face of changing environmental conditions.

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 Dingman Marsh Flooding Dam
Where does the data for Dingman Marsh Flooding 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.
