Summary
Completed in 1960, this earth dam stands at a height of 8 feet and has a storage capacity of 58 acre-feet. Located on TR-Tank Coulee, the dam's low hazard potential and current condition assessment of "Not Rated" indicate its stable and safe operation.
Managed by the Montana Department of Natural Resources and Conservation (DNRC), Blunt Ranches #2 is regulated, permitted, inspected, and enforced by the state. Despite its age, the dam has not been modified over the years, and its emergency action plan (EAP) status, risk assessment, and inundation maps are currently not available. With Congressman Greg Gianforte representing the area in Congressional District 00, the dam serves as a crucial water resource for the surrounding ranching community and ecosystem.
Water resource and climate enthusiasts will appreciate the significance of Blunt Ranches #2 in maintaining the water supply for firefighting, livestock, and aquatic life in the region. As a privately owned structure with state jurisdiction, the dam's low hazard potential and unassessed condition raise questions about its long-term resilience and the need for comprehensive risk management measures. With its historical importance and ongoing role in supporting local water needs, monitoring and assessment of Blunt Ranches #2 will be essential for ensuring its continued safety and effectiveness in the face of changing climate conditions.

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.
