Summary
With a primary purpose of irrigation, this earth dam stands at a height of 20 feet and has a hydraulic height of 17 feet. The dam has a storage capacity of 138 acre-feet and covers a surface area of 16 acres, serving the local community by providing water for agricultural needs.
Managed by the Nebraska Department of Natural Resources, Wiedenfeld Dam 1 is regulated, permitted, inspected, and enforced by state authorities to ensure its safety and compliance with regulations. Despite a low hazard potential, the dam's condition assessment is rated as poor, indicating a need for maintenance and potential improvements. With a maximum discharge capacity of 1550 cubic feet per second, the dam plays a crucial role in managing water resources in the region, highlighting its importance for both agricultural and environmental sustainability.
In light of recent inspections in August 2019, efforts to address the dam's condition and improve its safety are essential to mitigate any potential risks. As a key piece of infrastructure in the area, Wiedenfeld Dam 1 serves as a vital water resource for irrigation purposes, emphasizing the significance of proper maintenance and regulatory oversight to ensure its continued functionality and safety for the surrounding community and environment.

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.
