Summary
Built in 1985 by the USDA NRCS, this private-owned dam serves the primary purpose of irrigation, helping to sustain agriculture in the area. With a hydraulic height of 13 feet and a structural height of 16 feet, the dam boasts a storage capacity of 67 acre-feet and covers a surface area of 9 acres.
Managed and regulated by the Nebraska Department of Natural Resources, the Tredway Irrigation Dam is a vital component in the local water infrastructure. With a low hazard potential and a satisfactory condition assessment as of May 2016, the dam continues to provide reliable water storage and management for the surrounding community. The dam's location along the TR-Beaver Creek, under the oversight of the Omaha District of the US Army Corps of Engineers, ensures its effectiveness in maintaining water resources for irrigation purposes.
With a history of efficient operation and regular inspections, the Tredway Irrigation Dam remains a key asset for water conservation in the region. As a crucial piece of infrastructure designed to support agricultural activities, this earth dam with stone core continues to play a significant role in ensuring sustainable water management practices in Nebraska. Its construction and maintenance by the Natural Resources Conservation Service reflect a commitment to preserving water resources and adapting to the challenges of climate change 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.
