Summary

Completed in 1961, this dam stands at a height of 25 feet and has a storage capacity of 64 acre-feet. With a low hazard potential and a condition assessment of "Not Rated," Claribell #6 plays a crucial role in water resource management in the region.

Located in Congressional District 00, Montana, this dam is regulated by the DNRC and undergoes state permitting, inspection, and enforcement. The primary source agency for Claribell #6 is the state of Montana, with no federal agency involvement in its ownership, funding, or operations. Despite its low hazard potential, the dam has a maximum discharge capacity of 600 cubic feet per second and a spillway width of 1320 feet, ensuring effective water management during high flows.

Water resource and climate enthusiasts will appreciate the significance of Claribell #6 in supporting irrigation activities in the region. With its strategic location and design by USDA NRCS, this earth dam not only provides water storage for agricultural purposes but also contributes to flood control and water management on the TR-North Fork Woody Creek. As a state-regulated structure with a history dating back to the early 1960s, Claribell #6 stands as a testament to effective dam engineering and management practices in 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.
