Summary

Completed in 1962, this earth dam stands at a height of 9 feet and has a hydraulic height of 8.5 feet, creating a reservoir with a maximum storage capacity of 58 acre-feet. The dam spans 190 feet in length and is situated on Fuller Creek, a tributary of the nearby East Fish Lake.

With a low hazard potential and a satisfactory condition assessment as of 2012, East Fish Lake Dam poses minimal risk to surrounding communities. It is equipped with an uncontrolled spillway that is 4 feet wide, ensuring proper water discharge during peak flow events. The dam's inspection frequency is set at 5 years, with the last assessment conducted in May 2012. Despite its moderate risk assessment rating, the dam's risk management measures and emergency action plan status are not specified in the available data.

Overall, East Fish Lake Dam provides a vital recreational resource for the local area while maintaining a good level of safety and functionality. Its presence on Fuller Creek contributes to the ecological landscape of Montmorency County, Michigan, and underscores the importance of responsible water resource management in the face of changing climate conditions.

Condition Assessment

Satisfactory
No 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

High
Dams 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.
