Summary
Completed in 1960, this earth dam with a height of 12 feet and a length of 250 feet, has a storage capacity of 180 acre-feet, providing essential water management for the surrounding area. The dam's primary purpose is for recreation, offering a serene location for outdoor enthusiasts to enjoy.
Managed by a private entity, Sadilek Dam is regulated, permitted, inspected, and enforced by the Michigan Department of Environment, Great Lakes, and Energy. With a low hazard potential and a moderate risk assessment rating, the dam serves as a key infrastructure for water supply and management in the region. The dam's location in Gratiot County, Michigan, near the Pine River tributary, adds to its significance in the local ecosystem and water resource management.
Despite its age, Sadilek Dam remains a sturdy structure with a structural height matching its hydraulic height of 12 feet. With a surface area of 8 acres and a drainage area of 0.2 square miles, the dam plays a crucial role in water retention and flood control. As a focal point for outdoor recreation and water conservation efforts, Sadilek Dam stands as a testament to sustainable water resource management in Michigan's landscape.

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.
