Summary
Constructed in 1960, this earth dam stands at a height of 15.7 feet and has a storage capacity of 54.9 acre-feet, with a normal storage level of 15.9 acre-feet and a surface area of 5.4 acres. The dam plays a crucial role in mitigating flood hazards in the area, serving as a vital infrastructure for water resource management.
The dam, managed by Johnson Enterprises, is regulated by the Nebraska Department of Natural Resources, which ensures compliance with state permitting, inspection, and enforcement requirements. Despite its low hazard potential, the dam's condition assessment remains unrated as of its last inspection in June 2018. With a history of no reported modifications or incidents, the dam continues to provide essential flood protection for the surrounding community.
As a key component of the local water resource infrastructure, Johnson Enterprises Dam stands as a testament to the importance of private ownership in safeguarding against flood risks in Nebraska. With its strategic location and design, this earth dam remains a critical asset for climate enthusiasts and water resource professionals alike, highlighting the crucial role that private entities play in ensuring the resilience of our water management systems.

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.
