Summary
Situated on TR-Beaver Creek, this dam stands at 16 feet high with a length of 175 feet, providing a storage capacity of 96 acre-feet. Despite being classified as having a low hazard potential and not rated for condition assessment, Beaver Tooth is regulated, permitted, inspected, and enforced by the Montana Department of Natural Resources and Conservation (DNRC), ensuring its safety and compliance with state regulations.
This dam plays a crucial role in water resource management in the area, serving the local community and wildlife by providing essential resources for fire protection, agriculture, and fish habitat. Located in Valley County, Montana, Beaver Tooth is an integral part of the region's water infrastructure, contributing to the conservation and utilization of water resources in the area. With its strategic location and purposeful design, this dam exemplifies the intersection of human ingenuity and environmental stewardship in managing water resources for multiple beneficial uses.
As a significant structure in the Omaha District of the US Army Corps of Engineers, Beaver Tooth reflects a commitment to sustainable water management practices and the protection of natural ecosystems. While its primary purpose may be fire protection and stock water supply, this dam also serves as a small fish pond, highlighting its versatility and contribution to biodiversity in the region. With its historical significance and functional design, Beaver Tooth stands as a testament to the importance of responsible water resource management in the face of changing climate patterns and increasing water demands.

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.
