Summary
Constructed in 1960, this earth dam stands at a height of 18.7 feet and has a storage capacity of 77.8 acre-feet. Despite its low hazard potential, the dam's condition assessment in 2015 reported poor conditions, highlighting the need for maintenance and potential upgrades to ensure its continued effectiveness in mitigating flood risks in the region.
Managed by the Nebraska Department of Natural Resources, Jacobitz Dam plays a crucial role in protecting the surrounding areas from potential flooding events. The dam's primary purpose is flood risk reduction, with a normal storage capacity of 23.4 acre-feet and a surface area of 7.2 acres. While the dam has not undergone significant modifications in recent years, regular inspections are conducted to monitor its structural integrity and overall safety measures.
With its proximity to the Omaha District and oversight by the NE DNR, Jacobitz Dam serves as a vital infrastructure for flood control in the region. Despite its poor condition assessment in 2015, the dam's low hazard potential and the state's regulatory agency's involvement ensure that necessary actions are taken to maintain its functionality and safeguard the surrounding communities from potential flood risks. As water resource and climate enthusiasts, understanding the importance of structures like Jacobitz Dam in managing water flow and protecting against natural disasters is essential for sustainable water management practices in Nebraska.

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.
