Summary
Completed in 1979, this earth dam stands at a height of 26.7 feet with a hydraulic height of 24 feet and a structural height of 29.7 feet. With a normal storage capacity of 40.9 acre-feet and a maximum storage of 78.8 acre-feet, the dam covers a surface area of 4.5 acres and serves a drainage area of 0.23 square miles.
Despite its low hazard potential, Wehrman Dam 1386 is currently assessed to be in poor condition as of the last inspection in May 2016. The dam has a yearly inspection frequency of 5 and is regulated by the Nebraska Department of Natural Resources (NE DNR). While the dam has not undergone any modifications in recent years, its risk assessment, emergency action plan, and inundation maps status remain unknown. The dam's location on the TR-OX BOW CREEK, within the Congressional District 03 of Nebraska, underscores its importance in supporting agricultural activities in the region while highlighting the need for ongoing monitoring and maintenance to ensure its safety and functionality in the face of changing climate patterns.

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.
