Summary
Built in 1940, this earth dam stands at a height of 20 feet and has a storage capacity of 51 acre-feet. Situated on the TR-WILLOW COULEE river, this structure plays a vital role in managing water resources in the region for multiple purposes.
Owned privately, Couch Coulee #2 is regulated by the Montana Department of Natural Resources and Conservation (DNRC), with state jurisdiction, permitting, inspection, and enforcement in place to ensure its safety and compliance with regulations. With a low hazard potential and a condition assessment that is not currently rated, this dam provides a reliable water source for fire protection and agricultural needs in the area. Despite its age, Couch Coulee #2 continues to serve its intended purposes effectively.
For water resource and climate enthusiasts, Couch Coulee #2 represents a historical infrastructure that has been contributing to water management in Montana for over 80 years. Its location, dimensions, and purpose make it an interesting case study in the intersection of human intervention and natural resource utilization. As efforts continue to monitor and maintain the dam, its role in supporting the local ecosystem and community resilience remains crucial in the face of changing climate patterns.

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.
