Nixon No 2 dam
Nixon No 2
Nixon No 2, also known as Lower Nixon Dam, is a private-owned structure located in Boundary, Idaho, along Springs Bane Creek. This earth dam, primarily used for irrigation purposes, stands at a height of 12.7 meters with a storage capacity of 80.3 acre-feet. Despite its low hazard potential, the dam is in poor condition, as indicated by a 2016 assessment.
The dam features an uncontrolled spillway with a width of 6 meters and outlet gates consisting of slide (sluice gate) mechanisms. While it has not undergone significant modifications since its construction, Nixon No 2 is subject to state regulation, inspection, and enforcement by the Idaho Department of Water Resources. The risk assessment for the dam is rated as moderate (3), highlighting the need for ongoing monitoring and potential management measures to ensure its safety and functionality in the face of evolving climate conditions.
For water resource and climate enthusiasts, Nixon No 2 serves as a reminder of the intricate infrastructure supporting agricultural activities in the region and the importance of maintaining and upgrading such systems to withstand the impacts of changing environmental conditions. As a private dam under state jurisdiction, its management and upkeep are crucial for both water supply reliability and the safety of downstream communities. With its location in a remote area and limited associated structures, Nixon No 2 stands as a testament to the intersection of water resource management, infrastructure resilience, and climate adaptation in the face of potential hazards.

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 Nixon No 2
Where does the data for Nixon No 2 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.
