Flook Dam dam
Flook Dam
Located in Dexter, Michigan, along the Huron River, Flook Dam serves as a significant earth and gravity dam with a height of 11.8 feet and a length of 400 feet. Completed in 1965, this private dam provides a storage capacity of 6,000 acre-feet and plays a crucial role in managing water resources in the area. With a spillway width of 106 feet and a controlled spillway type, Flook Dam is designed to handle maximum discharges of up to 7,880 cubic feet per second, ensuring effective flood control measures for the surrounding region.
Managed by the Michigan Department of Environment, Great Lakes, and Energy (DEGLE), Flook Dam has a state-regulated status with regular inspections to maintain its satisfactory condition and significant hazard potential. The dam's risk assessment indicates a very high risk level, requiring stringent risk management measures to ensure its operational safety and reliability. Despite being a private structure, Flook Dam's importance in water resource management and climate adaptation efforts cannot be understated, making it a key asset in the overall infrastructure of the region.
With its strategic location and vital role in water storage and flood control, Flook Dam stands as a critical asset along the Huron River, contributing to the overall resilience of the local water infrastructure. As climate change continues to pose challenges to water resources and extreme weather events become more frequent, the effective management and maintenance of dams like Flook Dam are essential for ensuring the safety and sustainability of communities in Washtenaw County and beyond. The dam's regulated status, state inspections, and emergency action plans underscore the commitment to safeguarding the surrounding areas from potential risks and ensuring the efficient utilization of water resources for future generations.

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 Flook Dam
Where does the data for Flook 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.
