Summary
Completed in 1972 by the USDA NRCS, this private-owned earth dam spans 499 feet in length and reaches a height of 20 feet, providing essential protection for the surrounding area against potential flood events. With a storage capacity of 99.2 acre-feet and a normal storage level of 11.4 acre-feet, the dam plays a crucial role in managing water resources in the region.
Managed by the Nebraska Department of Natural Resources, the Lobner Group Dam is subject to state regulation, inspection, and enforcement to ensure its structural integrity and safety. Despite its low hazard potential, the dam's condition remains unrated as of the last inspection in April 2019. With a drainage area of 0.5 square miles and a maximum discharge capacity of 4621 cubic feet per second, the dam serves as a vital component in the local water management system, safeguarding nearby communities from the threat of flooding.
As a key asset for flood risk reduction in the region, the Lobner Group Dam underscores the importance of effective water resource management and infrastructure maintenance. With its significant storage capacity, strategic location along Ash Creek, and state-regulated operations, the dam exemplifies the collaborative efforts between private owners, government agencies, and designers in mitigating potential water-related hazards. As climate change continues to impact precipitation patterns and intensify flood risks, structures like the Lobner Group Dam play a crucial role in safeguarding communities and ecosystems from the detrimental effects of extreme weather events.

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.
