Summary
Completed in 1959, this dam serves multiple purposes, including fire protection, stock, and small fish pond management. With a height of 16 feet and a storage capacity of 84 acre-feet, the dam has a low hazard potential and has not been rated for its condition assessment.
Despite being a privately owned structure, B-6 #4 is regulated by the Montana Department of Natural Resources and Conservation (DNRC), with state jurisdiction, permitting, inspection, and enforcement all in place. The dam is situated in Custer County, Montana, and falls within Congressional District 00, represented by Greg Gianforte (R). While the dam has not been assessed for its condition recently, it remains in operation and meets the necessary state regulatory guidelines.
Water resource and climate enthusiasts will find B-6 #4 to be an interesting case study in private dam ownership and regulation. This structure showcases the importance of state oversight in ensuring the safety and functionality of dams, especially in rural areas where water management is crucial for various purposes. The location, design, and purpose of B-6 #4 offer valuable insights into the intersection of water resources, infrastructure, and environmental stewardship in Montana's diverse landscape.

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.
