Summary
Constructed in 1966 by USDA NRCS, this dam stands at a height of 35 feet and spans a length of 920 feet, providing a storage capacity of 750 acre-feet. The dam is regulated by the Nebraska Department of Natural Resources and undergoes regular inspections to ensure its structural integrity and functionality.
Situated on TR-PLUM CREEK, this dam plays a crucial role in mitigating flood risks in the region, with a low hazard potential and fair condition assessment as of the last inspection in 2016. Its strategic location in Liberty, Nebraska, within the Omaha District, highlights its significance in the local water resource management system. With a drainage area of 1.9 square miles and a maximum discharge capacity of 1200 cubic feet per second, Plum Creek 4-A serves as a key infrastructure for safeguarding the community against potential flooding events.
Overall, Plum Creek 4-A represents a vital component of Nebraska's water resource infrastructure, providing essential flood risk reduction measures for the surrounding area. Managed by the Natural Resources Conservation Service, this earth dam stands as a testament to effective collaboration between local government agencies and regulatory bodies in ensuring the resilience of water systems in the face of changing climate patterns. As water resource and climate enthusiasts, understanding the role of structures like Plum Creek 4-A is crucial in advocating for sustainable water management practices and enhancing community resilience to climate-related challenges.

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.
