Grand Rapids Detached Dike No 2 dam
Grand Rapids Detached Dike No 2
Grand Rapids Detached Dike No 2 is a historic structure located in Marinette, Michigan along the Menominee River. Built in 1909, this Earth dam stands at a height of 10 feet and stretches 300 feet in length, providing vital hydroelectric power and recreational opportunities for the surrounding area. The dam boasts a storage capacity of 2,150 acre-feet, with a maximum discharge capability to manage water flow effectively.
Managed by the Federal Energy Regulatory Commission, Grand Rapids Detached Dike No 2 has a low hazard potential and is currently in a condition assessment status of "Not Available." The dam serves as a crucial piece of infrastructure for the region, with its stone core and soil foundation ensuring stability and longevity. With no state jurisdiction or permitting required, this dam remains a key component in the water resource management system for Menominee County.
For water resource and climate enthusiasts, Grand Rapids Detached Dike No 2 represents a blend of historical significance and modern functionality. Its role in providing hydroelectric power and recreational opportunities underscores the importance of sustainable water management practices. As a federally regulated structure, it serves as a testament to the meticulous oversight and maintenance required to ensure the safety and efficiency of such critical infrastructure in the face of changing environmental conditions.
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 Grand Rapids Detached Dike No 2
Where does the data for Grand Rapids Detached Dike No 2 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.
