Summary
With a dam height of 12 feet and a storage capacity of 91 acre-feet, Belushi serves as a low hazard potential structure on the TR-Little Muddy Creek. The dam, managed by the Montana Department of Natural Resources and Conservation, is regulated, permitted, inspected, and enforced by the state to ensure its safety and compliance.
Despite being relatively small in size, Belushi plays a crucial role in providing water resources for fire protection and livestock in the area. The dam's location in Congressional District 00, Montana, under the jurisdiction of Omaha District of USACE, highlights its significance in water management. While the dam has not been formally rated for its condition, its low hazard potential underscores the importance of ongoing monitoring and maintenance to uphold its integrity and functionality for the community.
As water resource and climate enthusiasts, understanding the role of structures like Belushi in managing water supply and supporting local ecosystems is vital. With its modest yet essential functions, Belushi stands as a testament to the intersection of human needs, environmental stewardship, and regulatory oversight in ensuring sustainable water resource management in Montana.

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.
