Summary
This dam serves multiple purposes, including flood risk reduction and other water resource management functions. It stands at a height of 21 feet and has a storage capacity of 52 acre-feet, providing essential protection to the surrounding area from potential flooding events.
Managed by the local government and regulated by the Nebraska Department of Natural Resources, Plum Creek 5-5 has a low hazard potential and is deemed to be in satisfactory condition as of the last inspection in April 2017. With a drainage area of 0.2 square miles and a maximum discharge capacity of 181 cubic feet per second, this dam plays a crucial role in mitigating flood risks and ensuring the safety of the Liberty community. Its strategic location along Plum Creek underscores its significance in water resource management within the region.
Despite its relatively small surface area of 3 acres, Plum Creek 5-5 is a key infrastructure asset in the area, providing essential water resource management functions and safeguarding against potential flooding risks. With its compliance with state regulations and routine inspections, this earth dam continues to serve its purpose effectively, showcasing the importance of sustainable water resource management in ensuring 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.
