Sands Lake North Dam dam
Sands Lake North Dam
Sands Lake North Dam, located in Hill County, Montana, serves as a crucial irrigation structure diverting water from Beaver Creek. Built in 1911, this earth dam stands at a height of 11 feet and stretches 525 feet in length, with a storage capacity of 650 acre-feet. The dam plays a vital role in supporting agricultural activities in the region, with a normal storage capacity of 405 acre-feet and a maximum discharge rate of 110 cubic feet per second.
Despite its age, Sands Lake North Dam remains in a significant hazard potential category, with its condition yet to be officially assessed. The dam's last inspection dates back to June 1995, indicating a potential need for updated safety evaluations and risk assessments. While the dam is privately owned, it falls under the regulatory jurisdiction of the Montana Department of Natural Resources and Conservation (DNRC), ensuring that state standards and enforcement measures are in place for its operation and maintenance.
Enthusiasts of water resource management and climate resilience will find Sands Lake North Dam to be an intriguing case study in the intersection of historic infrastructure, agricultural sustainability, and regulatory oversight. As discussions around dam safety and risk management grow in importance, this dam stands as a reminder of the ongoing challenges and opportunities in ensuring the reliability and resilience of water infrastructure in the face of changing environmental conditions and evolving regulatory landscapes.

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 Sands Lake North Dam
Where does the data for Sands Lake North 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.
