Summary
Built in 1963 by USDA NRCS, this dam serves the primary purpose of flood risk reduction along Plum Creek. With a height of 24 feet and a hydraulic height of 21 feet, Plum Creek 4-D has a storage capacity of 222 acre-feet and covers a surface area of 14 acres.
Managed by the Nebraska Department of Natural Resources, Plum Creek 4-D is regulated, inspected, and enforced by the state to ensure its structural integrity and safety. The dam's condition assessment in June 2020 deemed it satisfactory with a low hazard potential. With a drainage area of 0.7 square miles and a maximum discharge capacity of 430 cubic feet per second, Plum Creek 4-D plays a crucial role in mitigating flood risks for the surrounding community.
Despite its age, Plum Creek 4-D continues to serve its purpose effectively, offering essential protection against potential flooding events in the region. With regular inspections and maintenance, this earth dam remains a vital infrastructure for flood risk reduction efforts in Pawnee County, 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.
