Curran-Barrett #1 dam
Curran-Barrett #1
Curran-Barrett #1 is a privately owned irrigation dam located in Hardy, Montana, along the TR-Dearborn River. Built in 1940, this earth dam stands at 15 feet high and has a storage capacity of 145 acre-feet. The dam is regulated by the Montana Department of Natural Resources and Conservation (DNRC), with state permitting, inspection, and enforcement in place to ensure its safety and compliance with regulations.
With a low hazard potential and a current condition assessment of "Not Rated," Curran-Barrett #1 plays a crucial role in water resource management in Lewis and Clark County, Montana. Although the dam's specific purposes are focused on irrigation, it also serves as a key structure for water storage and management in the area. As a part of the Walla Walla District, the dam contributes to the overall water infrastructure and plays a significant role in supporting agricultural activities in the region.
Despite its age, Curran-Barrett #1 continues to operate effectively and safely, with no recent modifications or inspections reported. While the dam's emergency action plan status and risk assessment details are not available, its presence and function remain vital for water supply and climate resilience in the area. As a symbol of sustainable water resource management, Curran-Barrett #1 stands as a testament to the importance of infrastructure in supporting agricultural and environmental needs in Montana.
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.
Plan around the weather

About Curran-Barrett #1
Where does the data for Curran-Barrett #1 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.
