Orchard Lake Dam dam
Orchard Lake Dam
Orchard Lake Dam, also known as Orchard Lake Overflow, was completed in 1968 in West Bloomfield, Michigan, with the primary purpose of flood risk reduction along the Orchard Lake Outlet. This private dam stands at a height of 8 feet with a hydraulic height of 4 feet and a length of 25 feet. It has a normal storage capacity of 1700 acre-feet, providing flood protection for the surrounding area.
The dam's spillway type is uncontrolled, with a width of 9 feet, and it has a low hazard potential with a satisfactory condition assessment as of the last inspection in November 2019. The risk assessment for Orchard Lake Dam is moderate, indicating a level 3 risk, but overall, the structure meets safety guidelines and has not required any significant risk management measures. Despite being privately owned, the dam plays a critical role in managing water levels and reducing flood risks in the region.
Water resource and climate enthusiasts interested in Orchard Lake Dam can appreciate its engineering design and functionality in mitigating flood risks along the Orchard Lake Outlet. With its modest size and effective flood risk reduction capabilities, this earth dam in Michigan serves as a vital infrastructure component in the local water management system.

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 Orchard Lake Dam
Where does the data for Orchard Lake 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.
