Mandeville Dam dam
Mandeville Dam
Mandeville Dam, located in Nestor, Michigan, is a private recreational structure that was completed in 1989. This earth dam stands at a height of 26 feet and spans 210 feet in length, serving primarily for recreational purposes. Situated on a tributary to Augres Creek, the dam boasts a normal storage capacity of 30 acre-feet and a maximum storage of 138 acre-feet, covering a surface area of 15 acres with a drainage area of 0.1 square miles.
Managed by the Michigan Department of Environment, Great Lakes, and Energy (DEGLE), Mandeville Dam is in satisfactory condition with a low hazard potential. The dam features an uncontrolled spillway and has undergone its last inspection in December 2006, with a scheduled inspection frequency of 5 years. Despite being classified as having a moderate risk level, the dam's risk management measures and emergency action preparedness are currently unspecified, posing potential areas for improvement and future assessment.
Water resource and climate enthusiasts interested in Mandeville Dam's design, construction, and operational details will find this structure in Ogemaw County, Michigan, a compelling subject for further exploration. With its recreational focus and state-regulated status, the dam offers a valuable case study for understanding the intersection of water management, environmental stewardship, and public safety considerations in the context of dam infrastructure within the Great Lakes 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 Mandeville Dam
Where does the data for Mandeville 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.
