Summary
This private Earth dam stands at a height of 12 feet with a length of 220 feet, providing a storage capacity of 95 acre-feet. Despite its low hazard potential, the dam's condition was assessed as unsatisfactory in 2017, highlighting the need for regular inspections and maintenance to ensure safety and longevity.
With a controlled spillway type and a maximum discharge capacity of 2600 cubic feet per second, Mission Creek Dam poses a very high risk in the event of failure, emphasizing the importance of risk management measures and emergency action plans. While the dam is primarily used for recreation, its critical role in flood control and water management cannot be overlooked. Its location in Isabella County adds to the significance of maintaining this structure to protect surrounding communities and the environment.
As water resource and climate enthusiasts monitor the condition of Mission Creek Dam and its associated structures, ongoing efforts to address the unsatisfactory assessment and mitigate risks are crucial. With a focus on safety, proper maintenance, and emergency preparedness, stakeholders can work towards preserving this essential infrastructure for both recreational enjoyment and environmental protection in the heart of Michigan.

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.
