Antelope Creek 60-A dam
Antelope Creek 60-A
Antelope Creek 60-A is a local government-owned dam located in Sheridan County, Nebraska, specifically in Gordon. Built in 1964 by the USDA NRCS, this earth dam stands 31 feet tall and spans 824 feet in length, with a storage capacity of 4841 acre-feet to reduce flood risk in the area. The dam is regulated, permitted, inspected, and enforced by the Nebraska Department of Natural Resources, ensuring its proper maintenance and operation.
With a low hazard potential and a satisfactory condition assessment as of 2019, Antelope Creek 60-A serves its primary purpose of flood risk reduction effectively. The dam's normal storage capacity is 446 acre-feet, covering a surface area of 91 acres and draining a 23-square mile watershed. Despite lacking specific spillway information, the dam can discharge up to 19000 cubic feet per second in case of overflow, providing crucial protection to the surrounding community.
For water resource and climate enthusiasts, Antelope Creek 60-A presents an intriguing case study of a well-maintained dam in rural Nebraska. With its close oversight by state regulatory agencies and the USDA NRCS, this dam showcases the importance of proper infrastructure to mitigate flood risks and protect downstream areas. As climate change continues to impact precipitation patterns, the role of structures like Antelope Creek 60-A becomes even more crucial in safeguarding communities and ecosystems from the threats of flooding.

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 Antelope Creek 60-A
Where does the data for Antelope Creek 60-A 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.
