Summary
Built in 1983, this earth dam serves primarily for recreational purposes, with a height of 7 feet and a storage capacity of 490 acre-feet. The dam spans 6700 feet along Collier Creek, offering not only a picturesque surface area of 355 acres but also contributing to the drainage area of 4.1 square miles.
Despite its significance, Milli-Ander Pond Dam faces challenges with its condition assessment rated as poor during the last inspection in May 2018. The dam's hazard potential is deemed low, but the risk assessment stands at a moderate level. As a state-regulated structure under the oversight of the Michigan Department of Environment, Great Lakes, and Energy, the dam requires regular inspections and enforcement to ensure public safety and environmental protection. With a moderate risk level and poor condition, the management of Milli-Ander Pond Dam remains a critical concern for water resource and climate enthusiasts in the region.
As enthusiasts closely monitor the state of Milli-Ander Pond Dam, efforts to address its poor condition and mitigate risks are essential. With a moderate risk level, the dam's structural integrity and maintenance become crucial factors in safeguarding the surrounding community and ecosystem. By staying informed and engaged in the management and regulation of this vital water resource, enthusiasts can play a role in ensuring the long-term sustainability and safety of Milli-Ander Pond Dam for future generations.

Dam Data Reference
Condition Assessment
SatisfactoryNo 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. Note: Rare or extreme event is defined by the regulatory agency based on their minimum
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. Investigations and studies are necessary.
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.
Not Available
Dams for which the condition assessment is restricted to approved government users.
Hazard Potential Classification
HighDams 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, environment 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.
Not Available
Dams for which the downstream hazard potential is restricted to approved government users.
