Crow Island Dam dam
Crow Island Dam
Crow Island Dam, located in Melbourne, Michigan, is a state-regulated structure under the jurisdiction of the Michigan Department of Environment, Great Lakes, and Energy (DEGLE). Completed in 1958, this dam stands at a height of 10 feet and serves the primary purpose of regulating the flow of a tributary to the Saginaw River. With a storage capacity of 4030 acre-feet, it plays a crucial role in managing water resources in the area.
The dam's spillway type is controlled, with a width of 2 feet, ensuring efficient water discharge when needed. Despite its low hazard potential and satisfactory condition assessment, the risk assessment categorizes it as having a very high risk level (1). The last inspection in 2015 indicated that the dam met safety guidelines, but there are no records of emergency action plans or inundation maps being prepared.
Crow Island Dam offers a glimpse into the intricate network of water infrastructure in Michigan, highlighting the importance of maintaining and monitoring such structures to mitigate potential risks. As climate change continues to impact water resources, understanding and safeguarding dams like Crow Island Dam becomes increasingly crucial for the sustainability of the surrounding ecosystems and communities.

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 Crow Island Dam
Where does the data for Crow Island 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.
