Summary
Situated on TR-Froze-to-Death Creek, this dam has a height of 13 feet and a length of 325 feet, with a storage capacity of 115 acre-feet. The dam is regulated by the Montana Department of Natural Resources and Conservation (DNRC) and is classified as having a low hazard potential.
Despite not being rated for its condition, Bn #9 is inspected, permitted, and enforced by the state regulatory agency, with emergency action plans potentially in place. The dam poses a low risk to surrounding areas and does not fall under the jurisdiction of the U.S. Army Corps of Engineers. With its primary purpose of protecting against wildfires and providing water for livestock and fish, Bn #9 serves as a vital resource in the region.
For water resource and climate enthusiasts, Bn #9 presents an intriguing case study of a privately owned dam in rural Montana. From its historical completion in the mid-20th century to its continued role in fire prevention and water management, this structure highlights the intersection of human infrastructure with natural ecosystems. As climate change impacts water availability and usage patterns, understanding the regulation and maintenance of dams like Bn #9 becomes increasingly important for sustainable resource management in the face of evolving environmental challenges.

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.
