Summary

Constructed in 1972 by USDA NRCS, this dam stands at a height of 31 feet and has a hydraulic height of 30 feet. With a structural height of 34 feet and a length of 537 feet, Plum Creek 2-C has a normal storage capacity of 53 acre-feet and a maximum storage of 255 acre-feet.

Managed and regulated by the Nebraska Department of Natural Resources, Plum Creek 2-C is in fair condition with a low hazard potential. The dam is inspected every 5 years, with the last assessment conducted in April 2020. Situated on TR-PLUM CREEK, this dam plays a crucial role in reducing flood risks in the region, with a maximum discharge capacity of 1059 cubic feet per second. Despite its age, Plum Creek 2-C continues to serve as a vital infrastructure for flood control in the area, showcasing the importance of effective water resource management in mitigating climate-related challenges.

As an essential part of the flood risk reduction infrastructure in Nebraska, Plum Creek 2-C represents a successful collaboration between local government and federal agencies. With its stone core and soil foundation, this earth dam demonstrates the importance of sustainable design and construction practices in water resource management. As climate change continues to impact the frequency and intensity of extreme weather events, dams like Plum Creek 2-C play a crucial role in protecting communities and ecosystems from the devastating effects of flooding.

Condition Assessment

Satisfactory
No 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

High
Dams 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.
