Summary
With a primary purpose of flood risk reduction and additional purposes like water storage, this private-owned earth dam spans 444 feet in length and reaches a height of 31 feet. Its low hazard potential and satisfactory condition assessment make it a critical infrastructure for the surrounding area, serving as a reliable barrier against potential flooding events on TR-Balls Branch.
Managed by the Nebraska Department of Natural Resources, the Wehrbein Dam boasts a normal storage capacity of 21 acre-feet and a maximum storage capacity of 61 acre-feet, ensuring ample water resources for the region. The dam's stone core and soil foundation contribute to its structural integrity, while its satisfactory condition and regular inspections uphold its reliability in safeguarding the community. Despite its modest surface area of 3 acres, the dam plays a crucial role in mitigating flood risks and maintaining water resources in the area.
As part of Congressional District 03 in Nebraska, the Wehrbein Dam stands as a vital component of the local infrastructure, overseen by the Omaha District of the US Army Corps of Engineers. With a maximum discharge of 55 cfs and a hydraulic height of 26 feet, the dam provides essential flood protection while supporting the region's water needs. Its strategic location and efficient design make it a key asset for water resource and climate enthusiasts seeking sustainable solutions for managing water resources and mitigating flood risks.

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.
