Autumn Ridge Detention Dam dam
Autumn Ridge Detention Dam
Autumn Ridge Detention Dam, located in Forest City, Michigan, is a crucial structure managed by the local government to address water resource management challenges in the area. Completed in 1982, this Earth-type dam stands at 11 feet high, with a length of 34 feet, and serves the primary purpose of water detention. The dam is situated on the Shanahan Drain, a tributary in Macomb County, and is designed to help control the flow of water and mitigate the risk of flooding in the region.
With a significant hazard potential and a moderate risk assessment rating, Autumn Ridge Detention Dam plays a vital role in safeguarding the community from potential water-related emergencies. While its condition assessment is currently not rated, the dam undergoes inspections every four years to ensure its structural integrity and operational effectiveness. The dam's spillway, with a width of 14 feet, serves as an uncontrolled release point for excess water, with a maximum discharge capacity of 400 cubic feet per second.
Water resource and climate enthusiasts would find Autumn Ridge Detention Dam an intriguing structure, serving as a key component in the local water management infrastructure. As a critical piece of the region's flood control measures, the dam's role in regulating water flow and reducing flood risks demonstrates the importance of sustainable water resource management practices in the face of changing climate conditions. Its presence on the Shanahan Drain highlights the collaborative efforts between local authorities and the community to address water-related challenges and enhance resilience to potential water emergencies.
Dam data reference
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 Autumn Ridge Detention Dam
Where does the data for Autumn Ridge Detention 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 Significant 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.
