Lyle Nejezchleb Dam dam
Lyle Nejezchleb Dam
Lyle Nejezchleb Dam is a privately owned structure located in Deweese, Nebraska, designed by the USDA NRCS and regulated by the Nebraska Department of Natural Resources. Completed in 1989, this earth dam stands at 22 feet in height and serves primarily for irrigation purposes along Liberty Creek. With a storage capacity of 54 acre-feet and a low hazard potential, the dam covers a surface area of 4 acres and drains a 0.4 square mile watershed.
Managed by the Natural Resources Conservation Service, Lyle Nejezchleb Dam has a fair condition assessment as of March 2020 and is inspected every five years. Its structural height reaches 30 feet, with a hydraulic height of 21 feet, and a length of 400 feet. Though lacking specific spillway information, the dam has a maximum discharge of 109 cubic feet per second and a normal storage capacity of 17 acre-feet. Located within the Omaha District, this dam plays a crucial role in supporting local irrigation needs in Nuckolls County, Nebraska.
For water resource and climate enthusiasts, Lyle Nejezchleb Dam offers a fascinating example of sustainable water management in Nebraska. With its earth construction and stone core, this structure represents a significant investment in agricultural irrigation infrastructure. Despite its low hazard potential, the dam's strategic location and design contribute to the efficient utilization of water resources in the region. As a key component of the local water management system, Lyle Nejezchleb Dam showcases the importance of responsible dam operation and maintenance in ensuring water security for agricultural activities in Nuckolls County.

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 Lyle Nejezchleb Dam
Where does the data for Lyle Nejezchleb 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.
