Summary
Constructed in 1952 by the USDA NRCS, this dam serves multiple purposes including fire protection, stock, and a small fish pond. With a height of 18 feet and a length of 500 feet, it provides a storage capacity of 92 acre-feet and has a low hazard potential.
Managed by the Montana Department of Natural Resources and Conservation (DNRC), W Miller #1 is regulated, permitted, inspected, and enforced by the state. The dam has a moderate risk assessment rating of 3, highlighting the importance of proper risk management measures. While the condition of the dam is currently not rated, it remains an essential resource for water management in the region and contributes to the overall ecological health of the area.
Located in McCone County, W Miller #1 is situated in a picturesque setting with a drainage area of 1.2 square miles. Despite not being under the jurisdiction of the US Army Corps of Engineers, the dam plays a crucial role in water resource management and climate resilience efforts in the region. With its multi-purpose design and regulated operation, W Miller #1 stands as a testament to the importance of sustainable water infrastructure for both human and environmental needs.

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.
