Summary
Built in 1949, this earth dam stands at a height of 6.7 feet and has a hydraulic height of 6.1 feet, providing a storage capacity of 160 acre-feet. The dam, sitting on the tributary to South Branch Flint River, offers a surface area of 22 acres and a drainage area of 4.3 square miles, making it an essential water resource in the region.
With a low hazard potential and a satisfactory condition assessment as of 2019, Sawdel Lake Dam ensures the safety of its surrounding community. The dam features an uncontrolled spillway with a width of 31 feet and a maximum discharge capacity of 260 cubic feet per second. Its risk assessment indicates a moderate level of risk, emphasizing the importance of regular inspections and maintenance to mitigate potential dangers. As a popular spot for recreational activities, Sawdel Lake Dam serves as a vital asset for both water resource management and climate enthusiasts in the area.
This earth dam, managed by the Michigan Department of Environment, Great Lakes, and Energy (DEGLE), continues to be a focal point for water conservation and outdoor leisure. Its historical significance, coupled with its functional design and strategic location, underscores the importance of sustainable water resource management in maintaining the integrity and safety of our natural environment. For water resource and climate enthusiasts, Sawdel Lake Dam stands as a testament to the intersection of human ingenuity and environmental stewardship in ensuring the resilience and vitality of our water systems.

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.
