Yellow Water Dike dam
Yellow Water Dike
The Yellow Water Dike in Montana is a crucial infrastructure designed for irrigation purposes along Yellow Water Creek. Built in 1938, this rockfill dam stands at a height of 11 feet and stretches over 545 feet, providing storage of up to 5100 acre-feet of water. With a drainage area of 55 square miles, the dam plays a vital role in managing water resources in the region, with a maximum discharge capacity of 180 cubic feet per second.
Located in Petroleum County, the Yellow Water Dike is regulated and inspected by the Montana Department of Natural Resources and Conservation, ensuring its structural integrity and operational efficiency. The dam has a high hazard potential, but its condition assessment in 2021 deemed it satisfactory. The last inspection in October 2021 indicated a regular inspection frequency of every 5 years, highlighting the commitment to maintaining the dam's safety and functionality.
Water resource and climate enthusiasts will appreciate the Yellow Water Dike's role in supporting local agriculture through irrigation and its significance in water management in the region. With its historical construction date, storage capacity, and regulatory oversight, this dam serves as a key piece of infrastructure in sustaining water resources and mitigating potential risks associated with floods or emergencies.

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 Yellow Water Dike
Where does the data for Yellow Water Dike 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.
