Summary

Built in 1941, this Public Utility-owned structure stands at 31 feet high and spans 316 feet in length, holding a storage capacity of 150 acre-feet. Operated under the oversight of the Nebraska Department of Natural Resources and regulated by the Federal Energy Regulatory Commission, Phillips plays a crucial role in water resource management in the area.

Situated along the Supply Canal in Lexington, Nebraska, Phillips is recognized for its low hazard potential and high risk assessment, indicating the importance of proper maintenance and emergency preparedness. Although the condition assessment is not currently available, regular inspections are conducted to ensure the dam's structural integrity and safety. With a history of federal oversight and state jurisdiction, Phillips serves as a vital component in the region's water infrastructure, contributing to both hydroelectric power generation and agricultural irrigation needs.

As a key player in the Kansas City District under the supervision of the Federal Energy Regulatory Commission, Phillips represents a collaborative effort between federal and state agencies to manage water resources effectively. With a focus on sustainability and risk management, this earth dam stands as a testament to the intersection of water resource management and climate resilience, highlighting the importance of infrastructure maintenance and emergency preparedness in the face of changing environmental conditions.

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.
