Summary
This Federal-owned dam on the Walsh Ditch/Walsh Creek serves as a Fish and Wildlife Pond, with a primary purpose of supporting aquatic ecosystems in the area. Standing at a height of 12 feet and a length of 19,425 feet, the earth dam is regulated by the Michigan Department of Environment, Great Lakes, and Energy (DEGLE) and undergoes regular inspections to ensure its structural integrity.
Despite its low hazard potential and fair condition assessment, Seney C-3 Pool Dam has undergone multiple structural modifications over the years to maintain its safety and functionality. The dam's controlled spillway and other controlled outlet gates help manage water levels, with a maximum discharge capacity of 575 cubic feet per second. In the event of an emergency, the dam's Emergency Action Plan (EAP) status and risk assessment are currently unspecified, highlighting the importance of continued monitoring and risk management measures to address potential safety concerns.
With its vital role in supporting local fish and wildlife habitats, Seney C-3 Pool Dam stands as a significant resource in the region. Ongoing efforts to ensure its safety and effectiveness underscore the importance of maintaining sustainable water management practices in the face of changing climate conditions. As water resource and climate enthusiasts, understanding the complexities of dam infrastructure like Seney C-3 Pool Dam is crucial for fostering resilience and protecting our natural ecosystems for future generations.

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.
