Redmon (Marshall) Perrin 1 dam
Redmon (Marshall) Perrin 1
Redmon (Marshall) Perrin 1, also known as Perrin #1, is a local government-owned dam located in Marshall, Michigan along the Kalamazoo River. Built in 1893 with an earth core and concrete structure, the dam stands at a height of 12 feet and stretches 150 feet in length. Its primary purpose is for hydroelectric power generation, with a normal storage capacity of 1,775 acre-feet over a surface area of 130 acres.
Managed by the Federal Energy Regulatory Commission, Redmon (Marshall) Perrin 1 has a high hazard potential due to its proximity to populated areas. Despite its age, the dam undergoes regular inspections to ensure its structural integrity and operational safety. The dam's spillway, an uncontrolled type with a width of 150 feet, helps regulate water flow and prevent overflow during peak discharge events.
With a drainage area of 352 square miles and a maximum discharge capacity of 4,200 cubic feet per second, Redmon (Marshall) Perrin 1 plays a crucial role in water resource management and flood control in the region. Its historical significance and ongoing maintenance efforts highlight the importance of sustainable infrastructure practices for climate resilience and water conservation.

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 Redmon (Marshall) Perrin 1
Where does the data for Redmon (Marshall) Perrin 1 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 High 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.
