Summary

Completed in 2008, this earthen dam stands at a height of 16 feet with a hydraulic height of 14 feet, providing a storage capacity of 165 acre-feet. With a controlled spillway and a maximum discharge of 120 cubic feet per second, the dam helps mitigate flood risks in the area.

Despite its low hazard potential and satisfactory condition assessment, Carrier Creek Structure F is subject to state regulation, permitting, inspection, and enforcement by the Michigan Department of Environment, Great Lakes, and Energy (DEGLE). The dam's last inspection took place in June 2016, with an inspection frequency of 5 years. The risk assessment for the dam is very high, emphasizing the importance of ongoing monitoring and management measures to ensure its continued effectiveness in flood risk reduction.

Located in a high-risk area with a very high risk rating, Carrier Creek Structure F plays a crucial role in protecting the surrounding community from potential flooding events. As a privately owned structure, it highlights the importance of private-public partnerships in managing water resources and climate-related risks. With its controlled spillway, storage capacity, and satisfactory condition, the dam serves as a vital infrastructure for flood control along Carrier Creek, contributing to the overall resilience of the region against natural disasters.

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.
