Janet Bentley Dam dam
Janet Bentley Dam
Janet Bentley Dam, located in Neligh, Nebraska, along the TR-Hail Creek, was completed in 2006 by the USDA NRCS. This privately owned earth dam stands at a height of 22 feet with a hydraulic height of 22 feet and a structural height of 25 feet. Its primary purpose is flood risk reduction, with a storage capacity of 152 acre-feet and a drainage area of 2.4 square miles. The dam has a low hazard potential and was last inspected in May 2017, receiving a satisfactory condition assessment.
Despite being a relatively small structure, Janet Bentley Dam plays a crucial role in mitigating flood risks in the Antelope County area. With its stone core and soil foundation, the dam spans 333 feet in length and covers a surface area of 11 acres. It is regulated by the Nebraska Department of Natural Resources and undergoes regular inspections and enforcement to ensure its safety and effectiveness in flood control. The dam is an essential part of the local water resource management system, providing protection to the surrounding community and infrastructure against potential flood events.
Janet Bentley Dam's strategic location and design contribute to its successful performance in flood risk reduction. With its low hazard potential, satisfactory condition assessment, and adherence to state regulations, the dam serves as a reliable asset in maintaining the safety and resilience of the Antelope County region. As climate change continues to impact water resources and weather patterns, the presence of well-maintained structures like Janet Bentley Dam becomes increasingly vital in safeguarding communities and ecosystems from the threats of flooding and water-related disasters.

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 Janet Bentley Dam
Where does the data for Janet Bentley 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.
