Summary
The dam serves various purposes, including flood control and water resource management, with a maximum storage capacity of 210 acre-feet and a surface area of 35 acres. Despite its low hazard potential and moderate risk assessment, the dam has not been rated for its condition assessment since its last inspection in 1981, raising concerns about its current state and maintenance needs.
Managed by the Michigan Department of Environment, Great Lakes, and Energy (DEGLE), Pool Two is regulated, permitted, inspected, and enforced by state authorities to ensure its safe operation and compliance with regulatory standards. With an uncontrolled spillway type and a maximum discharge capacity of 2600 cubic feet per second, the dam plays a crucial role in mitigating flood risks in the area. However, the lack of recent assessments and emergency preparedness plans raises questions about its readiness to handle potential threats and emergencies.
Located within the jurisdiction of the Buffalo District of the US Army Corps of Engineers, Pool Two is monitored for its risk management measures and operational effectiveness. The dam's association with the federal government and its primary purpose of "other" highlight its significance in the region's water resource infrastructure. As water resource and climate enthusiasts, understanding the importance of maintaining and assessing dams like Pool Two is essential for ensuring long-term water security and resilience in the face of changing climate conditions.

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.
