Tuttle Marsh Dam dam
Tuttle Marsh Dam
Tuttle Marsh Dam, located in East Tawas, Michigan, is a Federal-owned structure managed by the USDA Forest Service. Built in 1989, this Earth-type dam serves as a Fish and Wildlife Pond with a primary purpose of enhancing the local ecosystem. The dam stands at 7 feet high and spans a length of 11,800 feet, providing a storage capacity of 723 acre-feet and a surface area of 380 acres.
The dam's low hazard potential and moderate risk assessment make it a critical component of the Kunze Creek watershed, offering flood control and habitat support for various wildlife species in the area. Despite being uncontrolled, the dam's structure and design have withstood the test of time, ensuring the safety and integrity of the surrounding environment. With regular inspections and maintenance by the Forest Service, Tuttle Marsh Dam continues to play a crucial role in water resource management and climate resilience efforts in Iosco County.
For water resource and climate enthusiasts, Tuttle Marsh Dam presents a fascinating case study of how federal agencies like the USDA Forest Service contribute to ecological preservation and disaster prevention through innovative dam projects. From its construction to its current condition, this dam serves as a testament to the importance of sustainable water management practices in safeguarding natural ecosystems and communities against the impacts of climate change.

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 Tuttle Marsh Dam
Where does the data for Tuttle Marsh 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.
