Summary
Completed in 1976, this dam stands at a height of 21 feet with a hydraulic height of 20 feet, providing a maximum storage capacity of 362 acre-feet. With a satisfactory condition assessment and low hazard potential, Plum Creek 5-B contributes to the overall water resource management and climate resilience efforts in the region.
Managed by the local government and regulated by the Nebraska Department of Natural Resources, Plum Creek 5-B plays a crucial role in mitigating flood risks in the area. Its significant storage capacity and efficient design allow for the control of up to 1016 cubic feet per second of water discharge, ensuring the protection of downstream communities and infrastructure during extreme weather events. The dam's location on TR-PLUM CREEK and its connection to the Omaha District further highlight its importance in the regional water management system.
With a history of regular inspections and a comprehensive emergency action plan, Plum Creek 5-B exemplifies the effective collaboration between government agencies and stakeholders in safeguarding the local environment and communities from potential water-related hazards. Its strategic placement, structural integrity, and adherence to state regulations make it a valuable asset for water resource and climate enthusiasts seeking sustainable solutions for flood risk management in Nebraska.

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.
