Deiphobus dam
Deiphobus
Deiphobus, located in Cascade, Montana, is a privately owned Earth dam completed in 1953 for fire protection, stock, and small fish pond purposes. Situated on Crown Butte Creek, this dam stands at a height of 10 feet with a length of 200 feet, providing a storage capacity of 62 acre-feet. Despite its low hazard potential, Deiphobus is state regulated and subject to regular inspections, enforcement, and permitting by the Montana Department of Natural Resources and Conservation.
Owned by a private entity, Deiphobus serves as a vital resource for water management in the region, offering a reliable supply for various needs, including fire protection and agricultural activities. The dam's strategic location in Ulm, Montana, ensures a consistent water supply for local stakeholders while also contributing to the ecological balance of the area. With its modest storage capacity and operational efficiency, Deiphobus plays a crucial role in sustaining the surrounding ecosystem and supporting the community's water-related requirements.
As a significant infrastructure asset in the Walla Walla District, Deiphobus exemplifies the intersection of water resource management and climate resilience. While categorized as a low hazard structure, its strategic importance for fire protection and irrigation underscores the critical role that dams play in safeguarding communities and ecosystems. With its state-regulated status and adherence to inspection and enforcement protocols, Deiphobus stands as a dependable and essential component of Montana's water resource infrastructure.

About Deiphobus
Where does the data for Deiphobus 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 below 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.

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.
