Summary
Completed in 2001, this earth dam stands at a height of 8 feet and spans a length of 1000 feet along the TR-Elkhorn River. With a storage capacity of 58 acre-feet and a surface area of 10.4 acres, Wimmer Dam plays a crucial role in managing water resources in the region.
The dam, regulated by the Nebraska Department of Natural Resources, underwent modifications in 2012 to enhance its hydraulic and structural capabilities. Despite being categorized as having a low hazard potential and not rated on its condition assessment, Wimmer Dam is subject to regular inspections every 10 years to ensure its continued functionality. While the dam has not been designated as a USACE structure, it remains a vital component in the local water management system, safeguarding the surrounding area from potential flooding events.
Nestled in a picturesque setting near Scribner, Wimmer Dam serves as a testament to effective water resource management in Nebraska. With its strategic location along the Elkhorn River and its capacity to mitigate flood risks, this structure exemplifies the intersection of climate resilience and sustainable water infrastructure. As water resource and climate enthusiasts, the significance of Wimmer Dam lies not only in its engineering marvel but also in its role in safeguarding communities and ecosystems against the impacts of extreme weather events.

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.
