Lebo #2 Ne Dam dam
Lebo #2 Ne Dam
Located in Two Dot, Montana, the Lebo #2 Ne Dam is a privately owned structure designed by the USDA NRCS for irrigation purposes. Completed in 1969, this earth dam stands at a height of 15 feet and spans 760 feet in length. With a storage capacity of 4,735 acre-feet, the dam plays a crucial role in regulating water flow in the Big Elk Creek watershed.
The dam boasts a spillway width of 35 feet and an uncontrolled spillway type, with a maximum discharge capacity of 170 cubic feet per second. Despite being classified as having a significant hazard potential, the dam is currently assessed to be in fair condition. The last inspection in 2015 revealed no immediate concerns, but ongoing monitoring and maintenance are required to ensure the safety and efficiency of this vital water resource infrastructure.
For water resource and climate enthusiasts, the Lebo #2 Ne Dam serves as a prime example of the importance of proper dam management in mitigating risks and ensuring sustainable water usage. As climate change continues to impact water availability and quality, maintaining and regulating structures like the Lebo #2 Ne Dam will be essential in safeguarding water resources for future generations.

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 Lebo #2 Ne Dam
Where does the data for Lebo #2 Ne 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 Significant 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.
