Summary
Completed in 1950, this dam serves primarily for fire protection, stock watering, and as a small fish pond, with a storage capacity of 88 acre-feet. The dam stands at a height of 25 feet and spans 150 feet in length, providing essential water resources to the surrounding area.
Managed by the Montana Department of Natural Resources and Conservation (DNRC), Hutchison #1 is regulated and inspected by the state to ensure its safety and compliance with regulations. With a low hazard potential and a current condition assessment of "Not Rated," the dam plays a crucial role in water resource management in the region. While no associated structures or modifications have been reported, the dam continues to fulfill its purpose effectively.
Located in Powder River County, Montana, Hutchison #1 is a key component of the local water infrastructure, contributing to both agricultural and environmental needs. With its historical significance and ongoing functionality, this dam remains a vital resource for the community, showcasing the importance of sustainable water management practices in the face of changing climate conditions.

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.
