Hubbart dam
Hubbart
Hubbart is a concrete dam located on the Little Bitterroot River in Flathead, Montana. Built in 1923, it stands at a structural height of 130 feet and has a length of 503 feet. The dam's primary purpose is irrigation, with a storage capacity of 12,000 acre-feet. It is owned and operated by the Bureau of Indian Affairs, making it a Federal-owned structure.
The dam is classified as having a high hazard potential and a very high risk assessment rating. Despite its age, the condition assessment is listed as "Not Available," with the last inspection date recorded in 2012. The Emergency Action Plan (EAP) status is also not provided, raising concerns about the readiness and response capabilities in case of an emergency. With no state regulatory oversight or permitting, it is crucial for the Federal agency to ensure the safety and maintenance of this critical water resource infrastructure.
Hubbart Dam's location in the Seattle District underlines its significance in the region's water management system. As an essential component for irrigation, it plays a vital role in supporting agricultural activities in the area. With the potential risks associated with the dam highlighted, there is a pressing need for regular inspections, maintenance, and emergency preparedness measures to safeguard both the structure and the surrounding community from any potential hazards or risks posed by the dam.
Dam data reference
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 Hubbart
Where does the data for Hubbart 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 High 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.
