Summary

The dam, with a height of 36 feet and a hydraulic height of 34 feet, serves primarily for irrigation purposes in the area. Designed by the USDA NRCS, the dam is classified as an earth dam with a stone core and soil foundation. With a normal storage capacity of 434 acre-feet and a maximum storage capacity of 498 acre-feet, the dam plays a crucial role in water resource management in the region.

Managed by the Nebraska Department of Natural Resources, Farwell Reg Dam has a low hazard potential and is rated in satisfactory condition as of the last assessment in 2018. The dam, situated on TR-Oak Creek, covers a surface area of 31 acres and has a drainage area of 0.2 square miles. While the dam does not have a spillway or outlet gates, it undergoes regular inspections every five years to ensure its structural integrity and safety. With its strategic location and vital role in irrigation, Farwell Reg Dam stands as a testament to effective water resource management and climate adaptation efforts in the region.

Overall, Farwell Reg Dam serves as a critical infrastructure for water storage and irrigation in Howard County, Nebraska. With its earth dam structure and efficient design by the USDA NRCS, the dam provides essential water resource management capabilities for the local community. Regular inspections and maintenance ensure the dam's continued functionality and safety, highlighting the importance of proactive climate adaptation measures in sustaining water resources for future generations.

Condition Assessment

Satisfactory
No 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

High
Dams 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.
