Summary
Built in 1960, the dam stands at a height of 28.8 feet and has a storage capacity of 281.6 acre-feet. Its primary purpose includes flood risk reduction and other water resource management activities. The dam is primarily made of earth with stone core types and soil foundations.
Despite its low hazard potential, the dam's condition assessment was reported as poor during its last inspection in April 2017. With a drainage area of 0.86 square miles and a normal storage capacity of 24.7 acre-feet, Highway 4 Dam plays a crucial role in managing water resources in the region. The dam is under the jurisdiction of the Nebraska Department of Natural Resources and undergoes regular state inspections, permitting, and enforcement to ensure its structural integrity and operational effectiveness.
Water resource and climate enthusiasts will find Highway 4 Dam an intriguing structure due to its historical significance, design features, and the critical role it plays in flood risk reduction and water management in Nuckolls County, Nebraska. As a state-owned and state-regulated dam, it serves as a vital infrastructure for the surrounding community and highlights the importance of effective water resource governance and maintenance practices in ensuring the safety and sustainability of such structures in the face of changing climate conditions.

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.
