Summary
Built in 1955 by the USDA NRCS, this dam stands at a height of 24 feet and stretches 200 feet in length, providing fire protection, stock water, and a small fish pond for the area. With a storage capacity of 126 acre-feet, the dam serves as a crucial water resource for the surrounding community.
Despite its low hazard potential and moderate risk assessment, Big Bucks #7 is regulated and inspected by the Montana Department of Natural Resources and Conservation. The dam's uncontrolled spillway, with a width of 100 feet, ensures a maximum discharge of 500 cubic feet per second during flood events. While the dam's condition is currently not rated, its presence highlights the importance of proper water management and climate resilience strategies in the region.
As an integral part of the local water infrastructure, Big Bucks #7 serves as a testament to the collaboration between private owners and government agencies in ensuring water security and safety. With its historical significance and functional purpose, this dam represents a vital resource for both human and ecological needs in the area, emphasizing the importance of sustainable water management practices for future generations.

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.
