Summary
Completed in 1950, the earth dam stands at a height of 19.8 feet and spans 518 feet in length. With a primary purpose of flood risk reduction, the dam has a storage capacity of 56.5 acre-feet and covers a surface area of 7.2 acres, serving as a vital resource for managing water flow in the region.
Despite its significance in mitigating flood risks, the dam's condition assessment reveals a poor rating, with a hazard potential classified as low. The last inspection conducted in March 2020 highlighted the need for improvements to ensure the structure's safety and performance. While the dam is regulated by the Nebraska Department of Natural Resources and undergoes regular inspections, the data suggests a pressing need for maintenance and potential upgrades to enhance its effectiveness in protecting the surrounding communities and environment from flooding events.
As water resource and climate enthusiasts keep a close eye on infrastructure like Wiedel Dam 8672, the data underscores the importance of proactive maintenance and risk management measures to safeguard against potential hazards. With its strategic location along the TR-Little Blue River and role in flood risk reduction, the dam serves as a critical asset in the region's water management system. Moving forward, continued monitoring, assessment, and potential enhancements will be essential to ensure the dam's resilience and ability to meet the challenges posed by changing climate patterns and increasing water-related risks in the area.

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.
