Summary
Completed in 1968, this earth dam stands at a height of 13 feet and has a capacity to store 80 acre-feet of water. With a normal storage capacity of 25 acre-feet and a drainage area of 0.63 square miles, Jarchow Dam plays a crucial role in managing water resources in the region.
Managed by the Nebraska Department of Natural Resources, Jarchow Dam is inspected every five years and is classified as having a low hazard potential with a fair condition assessment. The dam's location on TR-SWAN CREEK in Jefferson County, Nebraska, ensures that it contributes to the protection and preservation of the surrounding environment and community. With its stone and buttress core types, Jarchow Dam serves as a vital infrastructure for water resource management and climate resilience in the area.
Overall, Jarchow Dam is a key component of the water infrastructure in Nebraska, providing flood risk reduction and water storage capabilities. With its fair condition assessment and low hazard potential, this earth dam built by the USDA NRCS continues to play a crucial role in maintaining water resources in the region. Supported by the Nebraska DNR and inspected regularly, Jarchow Dam stands as a testament to effective water resource management and climate adaptation efforts in the state.

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.
