Summary
Completed in 1980, this earth dam stands at a height of 16.6 feet and spans 363 feet in length, with a storage capacity of 85.9 acre-feet. Despite its low hazard potential, the dam's condition assessment in 2017 revealed poor structural integrity, prompting a need for further inspection and potential maintenance.
Managed by the Nebraska Department of Natural Resources, Johnson Properties Dam is subject to state regulation, permitting, inspection, and enforcement. The dam primarily serves purposes beyond flood control, with its primary purpose classified as "Other." With a drainage area of 0.29 square miles and a normal storage capacity of 40.3 acre-feet, the dam covers a surface area of 7.9 acres. Although it lacks a spillway type and associated locks, the dam's design includes stone core types and a soil foundation, contributing to its overall stability.
In the congressional district of Nebraska, Johnson Properties Dam stands as a vital infrastructure under private ownership, contributing to water resource management and climate resilience efforts in the region. Despite its poor condition assessment, the dam's strategic location and design underscore its importance in mitigating flood risks and ensuring the safety of surrounding communities along TR-School Creek.

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.
