Etb Waterway Dams dam
Etb Waterway Dams
Etb Waterway Dams, also known as "D," "E," and "F" Waterway Dams, are located in Gwinn, Michigan, along Green Creek. These private dams were completed in 1986 and serve various purposes, including flood control and water storage. With a height of 20 feet and a storage capacity of 83 acre-feet, these earth dams play a crucial role in managing water resources in the area.
The dams are regulated by the Michigan Department of Environment, Great Lakes, and Energy (DEGLE), with regular inspections ensuring their satisfactory condition and low hazard potential. Despite their age, the Etb Waterway Dams have been well-maintained and meet regulatory guidelines, providing a moderate level of risk assessment. The surrounding area benefits from the dams' ability to control water flow and mitigate potential flooding, making them essential infrastructure for the community.
With a history of effective operation and minimal risk, the Etb Waterway Dams stand as a testament to responsible water resource management. Their presence along Green Creek in Marquette County, Michigan, highlights the importance of maintaining and monitoring dams to ensure the safety and well-being of local residents and the surrounding environment. As climate change continues to impact water systems, these dams play a vital role in adapting to and mitigating its effects, showcasing the importance of sustainable infrastructure for a changing world.
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 Etb Waterway Dams
Where does the data for Etb Waterway Dams 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.
