Summary
Completed in 2003, this earth-type dam stands at a height of 16 feet and spans a length of 1175 feet, with a storage capacity of 93 acre-feet. Situated along the TR-N BR VERDIGRE CREEK, the dam plays a crucial role in managing water resources in the region.
Managed by the Nebraska Department of Natural Resources, Johnson Dam 2677 has a low hazard potential and is deemed to be in satisfactory condition as of the last assessment in April 2020. With a drainage area of 0.1 square miles and a maximum discharge capacity of 119 cubic feet per second, the dam serves as a vital infrastructure for the local community, ensuring the safety and sustainability of water resources in the area. The dam's location in the city of VERDIGRE adds to its significance in mitigating flood risks and maintaining water quality in the region.
Despite its private ownership, Johnson Dam 2677 is subject to state regulation, inspection, and enforcement, highlighting the commitment to ensuring its safety and functionality. The dam's structure, designed with stone core and soil foundation, reflects a combination of durability and efficiency in water management. With its strategic positioning and vital role in flood risk reduction, Johnson Dam 2677 stands as a key asset for water resource and climate enthusiasts in the Nebraska region.

Dam Data Reference
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.
