Summary
With a primary purpose of flood risk reduction, this dam stands at a height of 28 feet and has a storage capacity of 48 acre-feet. The dam's structural height reaches 33 feet, with a length of 1070 feet, serving to protect the surrounding area against potential flooding events.
Managed by the local government and regulated by the Nebraska Department of Natural Resources, Plum Creek 4-8 plays a crucial role in safeguarding the nearby city of LIBERTY against flood risks. Despite its low hazard potential, the dam's condition assessment is marked as poor, emphasizing the need for regular inspections and potential maintenance to ensure its continued effectiveness in flood risk mitigation. The dam's location along TR-PLUM CREEK highlights its strategic placement in the region's water resource management infrastructure.
Water resource and climate enthusiasts will appreciate the significance of Plum Creek 4-8 in contributing to flood risk reduction efforts in Nebraska. As a key structure designed to protect the surrounding area from potential inundation, this earth-type dam serves as a testament to the collaboration between local government and federal agencies in promoting water infrastructure resilience. With ongoing inspections and potential improvements, Plum Creek 4-8 remains a critical asset in the region's water resource management strategy, highlighting the importance of proactive measures in mitigating flood risks and ensuring community safety.

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.
