Summary

Completed in 1974, these dams have a structural height of 7 feet and a hydraulic height of 5 feet, with a total length of 2720 feet. The dams have a storage capacity of 460 acre-feet, with a normal storage of 122 acre-feet and a surface area of 71 acres.

These dams on the TR-STUTTS CR river are regulated by the Forest Service and have a low hazard potential, with a moderate risk assessment score of 3. The spillway type is uncontrolled, with a spillway width of 3 feet. The last inspection was conducted in September 2020, with a condition assessment of "Not Rated." Despite the dams being uncontrolled, the risk management measures for these structures are not specified, highlighting the need for ongoing monitoring and maintenance to ensure their continued safety and functionality for fish and wildlife conservation in the area.

Overall, Scotts Marsh Dike 2 & 3 play a crucial role in providing habitat for various species in the region and contribute to the overall water resource management in Schoolcraft, Michigan. With their strategic location and purposeful design, these dams serve as essential infrastructure for maintaining a healthy ecosystem and climate resilience in the area. Continued attention and monitoring are essential to ensure the long-term sustainability and effectiveness of these structures for the benefit of both wildlife and the local community.

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.
