Simple Simon Dam dam
Simple Simon Dam
Simple Simon Dam, located in Phillips County, Montana, is a gravity dam owned and managed by the Bureau of Land Management. The dam, situated on an unnamed drainage, stands at a structural height of 20 feet with a hydraulic height of 12 feet. It has a length of 254 feet and a storage capacity of 283.25 acre-feet, serving as a crucial water resource in the region. Despite its low hazard potential, the dam's condition is currently not rated, with the last inspection conducted in November 2018.
Constructed by the Bureau of Land Management, Simple Simon Dam plays a vital role in water management and conservation efforts in the area. With its unique design featuring buttress and stone core types, the dam not only provides essential storage capacity but also supports the surrounding ecosystem. Although it does not have a designated primary purpose listed, the dam contributes to flood control, irrigation, and recreational activities in the region.
As an integral part of the water infrastructure in Montana, Simple Simon Dam is a testament to the collaborative efforts of federal agencies in ensuring water security and environmental sustainability. With its strategic location and modest storage capacity, the dam continues to serve the community while adhering to regulatory standards set by the Bureau of Land Management. Despite not having a current condition assessment, ongoing inspections and maintenance practices are essential to ensure the dam's long-term functionality and safety for all stakeholders.

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 Simple Simon Dam
Where does the data for Simple Simon Dam 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.
