Henry Dam #1 dam
Henry Dam #1
Henry Dam #1, located in Galata, Montana, is a privately owned structure completed in 1948 for the primary purposes of fire protection, stock, and small fish pond. This earth dam stands at a height of 12 feet and has a length of 200 feet, providing a storage capacity of 373 acre-feet. It is regulated by the Montana Department of Natural Resources and Conservation (DNRC) and is inspected, permitted, and enforced by state authorities, ensuring its compliance with safety standards.
Situated on Strawberry Creek, Henry Dam #1 serves as a crucial water resource for the local community, offering low hazard potential and not currently rated for its condition assessment. Despite its age, the dam continues to fulfill its intended functions effectively, with a normal storage capacity of 157 acre-feet. The dam's location in Toole County, Montana, highlights its importance in providing essential services for fire protection and agricultural needs in the region.
With its modest size and low risk profile, Henry Dam #1 remains a vital infrastructure for water management in the area, supporting irrigation, livestock watering, and wildlife habitats. As climate change impacts water resources, the dam's role in ensuring water availability and resilience in the face of changing conditions becomes increasingly significant. As enthusiasts for water resources and climate adaptation, monitoring and maintaining structures like Henry Dam #1 are essential for sustainable water management in the region.

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 Henry Dam #1
Where does the data for Henry Dam #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.
