Summary
This dam, owned by the local government, serves a primary purpose of flood risk reduction and other functions. With a height of 28 feet and a length of 500 feet, Plum Creek 4-6 has a storage capacity of 103 acre-feet, benefitting the surrounding area by providing a normal storage capacity of 16 acre-feet and a drainage area of 0.46 square miles.
Managed and regulated by the Nebraska Department of Natural Resources, Plum Creek 4-6 stands as a crucial water resource infrastructure in the region. It has a low hazard potential and a condition assessment that is currently not rated. The dam has a hydraulic height of 25 feet and a structural height of 33 feet, contributing to the overall flood risk reduction efforts in the area. With a maximum discharge capacity of 400 cubic feet per second, Plum Creek 4-6 plays a vital role in protecting the surrounding community from potential water-related disasters.
As part of the Omaha District's water management system, Plum Creek 4-6 is a key component in the overall water infrastructure network. Its location in LIBERTY, Nebraska, along TR-TIPPS CREEK, highlights its strategic importance in managing water resources and mitigating flood risks in the region. With a history of successful operation and regular inspections, Plum Creek 4-6 exemplifies the efforts made by local authorities and the USDA NRCS to ensure the safety and sustainability of water resources 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.
