Oak Grove Millpond Dam dam
Oak Grove Millpond Dam
Located in Oak Grove, Michigan, the Oak Grove Millpond Dam stands as a historic structure that was completed in 1850. With a primary purpose of recreation, this earth dam spans 300 feet in length and reaches a height of 20 feet, creating a reservoir with a storage capacity of 430 acre-feet. Situated on Bogue Creek, the dam's controlled spillway has a width of 16 feet and a maximum discharge capacity of 1400 cubic feet per second, serving as a vital component for managing water flow in the area.
The dam, which is privately owned and state-regulated by the MICHIGAN DEGLE, poses a significant hazard potential due to its age and condition being labeled as "Not Rated." Despite being inspected last in January 1997, the dam's risk assessment is categorized as very high, warranting attention and potentially necessitating risk management measures to ensure the safety and stability of the structure. The surrounding area, with a drainage area of 35.35 square miles, relies on the Oak Grove Millpond Dam for recreational activities and water resource management, highlighting its importance within the local ecosystem.
As water resource and climate enthusiasts delve into the details of the Oak Grove Millpond Dam, its historical significance and current condition spark interest and concern. With a risk assessment indicating a high level of vulnerability, the dam's role in water storage and flow regulation underscores the need for continued monitoring and potential upgrades to mitigate any potential hazards. As stakeholders collaborate to address the dam's risk factors and ensure its long-term sustainability, the Oak Grove Millpond Dam remains a focal point for water resource management in Livingston County, Michigan.

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 Oak Grove Millpond Dam
Where does the data for Oak Grove Millpond 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 Significant 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.
