Summary
Completed in 1930, this dam serves multiple purposes including fire protection, stock, and a small fish pond. With a dam height of 20 feet and a storage capacity of 55 acre-feet, Fogey #1 has a low hazard potential and is currently rated as "Not Rated" in terms of condition assessment.
Managed by the Montana Department of Natural Resources and Conservation (DNRC), Fogey #1 is regulated and inspected regularly to ensure its safety and functionality. Situated in Congressional District 00, Montana, this dam plays a crucial role in water resource management in the region. While the dam has not been modified in recent years and lacks certain assessment data, it remains an important structure for water supply and ecosystem support in the area.
Enthusiasts interested in water resources and climate in Montana will find Fogey #1 to be a fascinating case study of a privately owned dam with multiple uses. With its historical significance dating back to the early 20th century, this dam provides insights into the challenges and opportunities associated with managing water infrastructure in a rural setting. Despite its low hazard potential, ongoing regulatory oversight ensures that Fogey #1 continues to contribute to the local community's water needs while also supporting ecological stability in the region.

Dam Data Reference
Condition Assessment
SatisfactoryNo 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. Note: Rare or extreme event is defined by the regulatory agency based on their minimum
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. Investigations and studies are necessary.
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.
Not Available
Dams for which the condition assessment is restricted to approved government users.
Hazard Potential Classification
HighDams 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, environment 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.
Not Available
Dams for which the downstream hazard potential is restricted to approved government users.
