Summary

Built in 1950, this earth dam stands at 30 feet tall and has a storage capacity of 244 acre-feet, primarily serving purposes such as fire protection and stock or small fish pond management. Despite being classified as low hazard potential, the dam is regulated by the Montana Department of Natural Resources and Conservation (DNRC) and undergoes regular inspections, permitting, and enforcement to ensure its safety and functionality.

Situated in Rosebud County, Bs Kincheloe is overseen by private owners and falls within the jurisdiction of the state of Montana. With a maximum storage capacity of 244 acre-feet and a normal storage level of 178 acre-feet, this dam plays a crucial role in water resource management in the region. While its condition assessment is currently marked as "Not Rated," the dam is continuously monitored for any potential risks or hazards, with emergency action plans in place to address any unforeseen events.

With its strategic location and historical significance dating back to the mid-20th century, Bs Kincheloe stands as a testament to the importance of water infrastructure in sustaining local ecosystems and communities. As water resource and climate enthusiasts, understanding the role of structures like Bs Kincheloe in maintaining water supply, fire protection, and wildlife habitats is essential for promoting sustainable practices and ensuring the resilience of our water systems in the face of changing environmental conditions.

Condition Assessment

Satisfactory
No 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

High
Dams 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.
