Summary
The dam, completed in 1973, serves primarily for recreational purposes along Latter Creek. With a height of 15 feet and a length of 500 feet, the dam boasts a storage capacity of 100 acre-feet and a spillway width of 30 feet. Despite being uncontrolled, the spillway type and low hazard potential classify Latter Creek Dam as a moderate risk structure.
Managed by the Michigan Department of Environment, Great Lakes, and Energy (DEGLE), the dam is subject to regular inspections, permitting, and enforcement to ensure its safety and compliance with state regulations. While the condition assessment of the dam is currently rated as "Not Rated," the risk assessment deems it as having a moderate risk level. With a drainage area of 0 and a maximum discharge of 300 cubic feet per second, Latter Creek Dam remains an important structure for water resource management and climate enthusiasts in the region.
Enthusiasts interested in water resource management and climate change can appreciate Latter Creek Dam as a recreational structure that also plays a crucial role in maintaining the water levels along Latter Creek. While the dam has not been modified in recent years, its risk management measures and regular inspections by state agencies ensure its continued functionality and safety. With a location in Iosco County, Michigan, the dam serves as a key point of interest for those studying the impact of dams on local ecosystems and water resources in the region.

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.
