Summary
This privately owned Earth dam stands at a height of 30 feet and has a structural height of 35 feet, with a capacity to store up to 526 acre-feet of water. The dam covers a surface area of 32 acres and serves a drainage area of 11.6 square miles.
Despite its important role in providing water for irrigation, Lundy Dam is currently assessed as being in poor condition with a significant hazard potential. The dam is regulated by the Nebraska Department of Natural Resources and undergoes regular inspections, with the last assessment conducted in May 2020. The dam's emergency action plan status and risk management measures are currently unreported, raising concerns about its ability to withstand potential hazards.
With its history dating back over seven decades, Lundy Dam serves as a crucial water resource infrastructure in the region. However, its poor condition and significant hazard potential highlight the urgent need for maintenance and risk assessment to ensure the safety and reliability of this vital water storage facility for the local 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.
