Redridge Dam dam
Redridge Dam
Redridge Dam, located in Redridge, Michigan, is a significant structure built in 1902 for the primary purpose of recreation. The dam, constructed with a Timber Crib design, stands at a height of 50 feet and stretches 228 feet in length, holding a storage capacity of 1480 acre-feet. Situated on the Salmon Trout River, the dam serves as a popular spot for outdoor enthusiasts to engage in various recreational activities.
Managed by the local government, Redridge Dam falls under the jurisdiction of the Michigan Department of Environment, Great Lakes, and Energy (DEGLE) for regulation, permitting, inspection, and enforcement. The dam has been assessed to be in fair condition as of the last inspection in May 2014, with a significant hazard potential and a moderate risk level. Despite its age, the dam continues to provide essential functions in terms of water storage and recreational opportunities for the community.
With a spillway width of 28 feet and an uncontrolled spillway type, Redridge Dam remains a vital structure within the Detroit District of Michigan. While the dam has not undergone significant modifications over the years, it continues to be a focal point for water resource and climate enthusiasts, offering a glimpse into the engineering marvels of the past and the importance of sustainable water management practices for the future.
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 Redridge Dam
Where does the data for Redridge 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.
