Antholz Dam dam
Antholz Dam
Antholz Dam, located in Nemaha, Nebraska, is a privately owned earth dam designed by USDA NRCS. Completed in 2012, the dam serves primarily for grade stabilization on TR-Muddy Creek. With a height of 26 feet and a storage capacity of 154.6 acre-feet, the dam plays a crucial role in managing water resources in the area, with a drainage area of 0.77 square miles.
The dam's structural height reaches 31 feet, with a hydraulic height of 25.28 feet, ensuring its efficiency in flood control and water management. The dam has a low hazard potential and was last inspected in May 2019, with a satisfactory condition assessment. The surrounding surface area of 5.56 acres provides a habitat for various wildlife and vegetation, contributing to the ecological balance of the area.
Antholz Dam stands as a testament to effective water resource management and climate resilience efforts in the region. With its grade stabilization purpose and state-regulated status, it showcases the collaboration between private entities and regulatory agencies in safeguarding water resources and mitigating potential risks. The dam's strategic location and design reflect a commitment to sustainable practices and serve as a vital infrastructure for ensuring water security in Nemaha, Nebraska.

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 Antholz Dam
Where does the data for Antholz 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.
