Summary

The reservoir has a dam height and hydraulic height of 25 feet, with a storage capacity of 50 acre-feet and a normal storage level of 33 acre-feet. Situated on Yankee Doodle Creek, the reservoir serves as a vital resource for the community of Butte, Montana, providing water for various uses while also contributing to the local ecosystem.

Managed by the Montana Department of Natural Resources and Conservation (DNRC), Moulton Reservoir #2 is regulated, inspected, and enforced by state authorities to ensure its safe operation and maintenance. Despite being classified as having low hazard potential and not yet rated for condition assessment, the reservoir plays a crucial role in water resource management in the region. With its strategic location and capacity to store water, Moulton Reservoir #2 remains a valuable asset for mitigating the impacts of climate change and supporting sustainable water use practices in the area.

As an earth dam structure with a length of 300 feet, Moulton Reservoir #2 has been designed to withstand various hydrological conditions and provide reliable water storage for the surrounding community. While further assessments and risk management measures may be needed to enhance its resilience, the reservoir stands as a testament to human ingenuity in harnessing and managing water resources for multiple purposes. Climate enthusiasts and water resource experts can appreciate the importance of Moulton Reservoir #2 in safeguarding water supplies and promoting ecological balance in the region.

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.
