Summary
Built in 1970 by USDA NRCS, this earth dam stands at a height of 14 feet and spans 340 feet in length. It offers a storage capacity of 76 acre-feet, with a normal storage level of 41 acre-feet and a surface area of 6.9 acres.
The dam is regulated, permitted, inspected, and enforced by the Michigan Department of Environment, Great Lakes, and Energy (DEGLE). It has an uncontrolled spillway with a width of 21 feet and a maximum discharge of 115 cubic feet per second. The hazard potential of the dam is classified as low, with a satisfactory condition assessment conducted in December 2005.
Although Topski Dam has not undergone any significant modifications since its completion, it remains a moderate risk structure with a risk assessment rating of 3. With its scenic location and recreational opportunities, this dam serves as both a water resource and climate enthusiast's destination to appreciate the balance between human infrastructure and natural ecosystems in the Michigan landscape.

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.
