Lobner Group Dam dam
Lobner Group Dam
Located in Garden County, Nebraska, the Lobner Group Dam stands as a testament to effective flood risk reduction efforts. 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.

Condition Assessment
- Satisfactory
- No 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.
- 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.
- 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.
Hazard Potential Classification
- High
- Dams 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, environmental 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.

About Lobner Group Dam
Where does the data for Lobner Group Dam come from?
Structural and regulatory data come from the U.S. Army Corps of Engineers' National Inventory of Dams (NID). Weather forecast comes from NOAA / yr.no -- the same feed Snoflo's iOS app uses.
How often is the report updated?
NID structural data refreshes annually as the Corps publishes updated assessments. The weather forecast refreshes throughout the day.
What does the Low hazard rating mean?
The Corps of Engineers' hazard potential classification grades probable consequences if the dam fails: High = probable loss of human life; Significant = no probable loss of human life but possible economic loss / environmental damage; Low = no probable loss of human life, only minor economic / environmental losses. See the Dam Data Reference card above for the full definitions.
What's "% of normal"?
The current storage value compared to the historical average storage on this calendar day. 100% = right on average; values above 100% mean above-normal storage (wet year); values below mean below-normal (dry year or drought).
Can I get alerts when storage crosses a threshold?
Yes -- alerts are managed in the Snoflo iOS app. Favorite this dam, set a threshold, and you'll get a push the moment conditions cross.
