Summary

Built in 1886, this dam serves multiple purposes including fish and wildlife pond management, flood risk reduction, navigation, recreation, and water supply. With a dam height of 23 feet and a structural height of 22 feet, Pine River Dam has a storage capacity of 187,700 acre-feet and a normal storage capacity of 101,340 acre-feet. The dam is situated on the Pine River and is managed by the US Army Corps of Engineers.

Due to its high hazard potential, Pine River Dam is subject to regular inspections and risk management measures by the US Army Corps of Engineers. The dam has a controlled spillway and a maximum discharge capacity of 16,300 cubic feet per second. In the event of an emergency, an Emergency Action Plan (EAP) is in place, which meets guidelines and includes inundation maps. The Corps works closely with local emergency managers to ensure public safety and to update the EAP regularly.

Overall, Pine River Dam plays a crucial role in managing water resources in the region, and the US Army Corps of Engineers is committed to monitoring and maintaining the dam to mitigate flood risks and ensure its structural integrity. With ongoing risk management measures and emergency preparedness, Pine River Dam continues to serve as a vital infrastructure for the community while protecting against the potential dangers associated with severe weather events and fluctuating water levels.

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.
