Dte Energy Greenwood Cooling Reservoir dam
Dte Energy Greenwood Cooling Reservoir
Dte Energy Greenwood Cooling Reservoir, located in Avoca, Michigan, is a vital water resource for the region, primarily serving as a water supply source. Completed in 2016, this earth dam structure stands at a height of 16 feet, with a hydraulic height of 14 feet, and a length of 11,340 feet. With a maximum storage capacity of 1,050 acre-feet and a normal storage capacity of 500 acre-feet, this reservoir covers a surface area of 153 acres and drains an area of 0.25 square miles.
The reservoir's spillway, measuring 40 feet in width, is uncontrolled, and the structure has a low hazard potential with a satisfactory condition assessment. Despite being a moderate risk facility, with a risk level of 3, the Dte Energy Greenwood Cooling Reservoir has not had any recent modifications or inspections. The site is not regulated by the state and does not have a designated emergency action plan, but overall, it plays a crucial role in providing water for the surrounding area. For water resource and climate enthusiasts, this reservoir represents a key component of the region's water infrastructure.
Overall, the Dte Energy Greenwood Cooling Reservoir serves as a significant water supply source in St. Clair County, Michigan, contributing to the region's water resources and infrastructure. With its impressive storage capacity and surface area, the reservoir plays a vital role in ensuring water availability for various purposes. While it may pose a moderate risk, the structure's low hazard potential and satisfactory condition assessment indicate that it continues to function effectively in meeting the water supply needs of the community. For those interested in water resources and climate, this reservoir provides an intriguing case study of water management and infrastructure development in the region.

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 Dte Energy Greenwood Cooling Reservoir
Where does the data for Dte Energy Greenwood Cooling Reservoir 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.
