Summary
Completed in 1964, this earth dam stands at a height of 32 feet and stretches 570 feet in length, creating a recreational reservoir with a storage capacity of 6,800 acre-feet. The dam is situated on Peterson Creek, which has a drainage area of 6.1 square miles and a maximum discharge of 100 cubic feet per second.
The significant hazard potential of Lake Ogemaw Dam is mitigated by its satisfactory condition assessment as of August 2020. The dam operates with an uncontrolled spillway type, with a width of 34 feet. While the risk assessment categorizes the dam as moderate, with an assigned rating of 3, the structure is regularly inspected by the Michigan Department of Environment, Great Lakes, and Energy (DEGLE) to ensure compliance with state regulations. The dam's emergency action plan (EAP) status and adherence to guidelines remain unspecified, indicating areas for potential improvement in risk management measures.
For water resource and climate enthusiasts, Lake Ogemaw Dam represents a vital infrastructure that not only provides recreational opportunities but also serves as a crucial component in managing water flow along Peterson Creek. As a privately owned facility under state jurisdiction, the dam's role in flood control and water storage underscores the importance of regular inspections and adherence to safety protocols to sustain its functionality and minimize potential risks to downstream communities. The ongoing monitoring and maintenance efforts by regulatory agencies aim to ensure the continued safety and efficiency of Lake Ogemaw Dam in the face of evolving environmental challenges.

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.
