Summary
Completed in 1970, this earthen dam stands at a height of 21 feet, with a hydraulic height of 21 feet and a structural height of 22 feet. With a length of 539 feet and a maximum storage capacity of 140 acre-feet, Wiedel Dam serves the primary purpose of flood risk reduction, protecting the surrounding areas from potential water-related disasters.
Managed by the Nebraska Department of Natural Resources, Wiedel Dam has a low hazard potential and is currently in satisfactory condition as of the last assessment in April 2019. The dam has a drainage area of 1.1 square miles and a normal storage capacity of 30 acre-feet. With a maximum discharge rate of 296 cubic feet per second, the dam plays a crucial role in managing water levels and mitigating flood risks in the region. Additionally, the dam is subject to regular state inspections, permitting, and enforcement to ensure its continued safe operation.
Wiedel Dam, nestled along TR-SPRING CREEK in Hebron, Nebraska, is a vital infrastructure supported by the Natural Resources Conservation Service. In the event of an emergency, the dam has designated emergency contacts and an Emergency Action Plan (EAP) in place to guide response efforts. With its strategic location, design, and operational protocols, Wiedel Dam stands as a key asset in the region's water resource management and climate resilience efforts.

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.
