Summary
Built in 1959 by the USDA NRCS, this earth-type dam stands at 40 feet in height and spans 946 feet in length. With a storage capacity of 137 acre-feet, it serves to protect the surrounding area from potential flooding events, with a high hazard potential but a satisfactory condition assessment as of August 2020.
Managed by the local government, specifically the Nebraska Department of Natural Resources, Plattsmouth 10-A is subject to state regulations, permitting, inspections, and enforcement to ensure its proper functioning and safety. Situated within the Kansas City District, this dam plays a crucial role in mitigating flood risks and safeguarding the community of Plattsmouth. As a key component of flood control infrastructure, it highlights the importance of proactive measures in water resource management and climate resilience efforts.
With a primary purpose of flood risk reduction, Plattsmouth 10-A symbolizes the collaborative efforts between federal agencies, local governments, and designers like the USDA NRCS in safeguarding communities and ecosystems against the impacts of extreme weather events. As climate change continues to pose challenges to water resources, the significance of structures like Plattsmouth 10-A in managing flood risks and enhancing resilience becomes increasingly apparent. Its role in protecting lives, property, and critical infrastructure underscores the importance of sustainable water management practices in the face of a changing climate.

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.
