Sidney Dam dam
Sidney Dam
Sidney Dam, located in Carter, Montana, is a gravity dam with a structural height of 32 feet and a hydraulic height of 28 feet. Built by the Bureau of Land Management, this dam serves as a vital structure in an unnamed drainage area with a storage capacity of 100 acre-feet. Despite its low hazard potential, Sidney Dam plays a crucial role in managing water resources in the region, with a surface area of 10.96 acres and a drainage area of 0.3 square miles.
Owned and funded by the Bureau of Land Management, Sidney Dam has not been rated for its condition assessment. However, it is inspected every five years to ensure its safety and functionality. With no associated structures and a primary purpose that is unspecified, Sidney Dam stands as a testament to effective water resource management in Montana. Its location and design reflect the commitment of federal agencies in maintaining critical infrastructure for the benefit of the surrounding communities.
Sidney Dam, constructed with buttress and stone core types, represents a collaborative effort between federal agencies to regulate, inspect, and operate this essential water management structure. While its specific purposes and completion date are not provided, Sidney Dam's presence underscores the importance of sustainable water resource management in the face of changing climates. As water resource and climate enthusiasts, understanding and appreciating the role of dams like Sidney Dam is crucial in ensuring the resilience of our water infrastructure 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.
Plan around the weather
Same NOAA / yr.no feed Snoflo's iOS app uses. Watch the precipitation column on the meteogram -- rain on the basin upstream typically lifts inflow 24-72 hours later.

About Sidney Dam
Where does the data for Sidney 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.
