Summary

Completed in 1940, this earth dam structure stands at a height of 34 feet and has a storage capacity of 3,889 acre-feet. With a primary purpose of irrigation, the canal serves as a crucial water resource for farmers in Teton County, Montana.

Managed by the Department of Natural Resources and Conservation (DNRC), Farmers Coop Canal Co is regulated, inspected, and enforced by the state, ensuring its operational efficiency and safety. The low hazard potential of the dam indicates minimal risk, although its condition assessment is currently not rated. Despite lacking a formal Emergency Action Plan (EAP) and inundation maps, the canal system continues to meet the irrigation needs of the local agricultural community.

As water resource and climate enthusiasts, the data on Farmers Coop Canal Co provide valuable insights into the importance of sustainable water management practices in agricultural settings. By understanding the infrastructure, maintenance, and regulatory aspects of irrigation systems like this, we can better appreciate the interconnectedness of water resources, climate resilience, and food production in rural communities like Farmington, Montana.

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.
