Summary
With a stone construction and a height of 10 feet, the dam holds a normal storage capacity of 8,650 acre-feet and a maximum storage of 11,600 acre-feet. The dam spans 120 feet in length and sits on the Clary Lake Stream, serving as a critical water resource for the area.
Managed by a private owner, the Clary Lake Dam is regulated by the state agency MEMA and undergoes regular inspections to ensure its structural integrity and safety. With a low hazard potential and a condition assessment that is currently not rated, the dam plays a vital role in fire protection, stock maintenance, and small fish pond management in addition to its hydroelectric function.
Enthusiasts of water resources and climate will find the Clary Lake Dam an intriguing example of historic infrastructure supporting both human needs and ecological balance. Its presence on the Clary Lake Stream not only provides essential services but also serves as a reminder of the interconnectedness between water management, energy generation, and environmental stewardship in the region.

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.
