Groveland Dam #8 dam
Groveland Dam #8
Groveland Dam #8, also known as Groveland Mine Tailings Dam #8, is a state-regulated earth dam located in Loretto, Michigan. Completed in 1977, this dam serves the primary purpose of recreation, offering opportunities for outdoor enthusiasts to enjoy activities such as boating and fishing on the Pine Creek river. With a height of 60 feet and a length of 2000 feet, Groveland Dam #8 has a storage capacity of 11,232 acre-feet and covers a surface area of 390 acres.
Despite being classified as having a low hazard potential and fair condition assessment, Groveland Dam #8 is subject to regular inspections by the Michigan Department of Environment, Great Lakes, and Energy (DEGLE) to ensure its structural integrity and safety. The dam features an uncontrolled spillway with a width of 12 feet, and its risk assessment is moderate. The surrounding area is at a moderate risk level (3), prompting the need for ongoing risk management measures to mitigate potential hazards and ensure the safety of the community.
Overall, Groveland Dam #8 stands as a vital water resource in Dickinson County, Michigan, providing both recreational opportunities and essential water storage for the region. By adhering to state regulations and undergoing regular inspections, this dam continues to play a crucial role in water management and environmental protection efforts in the area, making it a significant site for water resource and climate enthusiasts to appreciate and monitor.
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 Groveland Dam #8
Where does the data for Groveland Dam #8 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.
