Summary

Built in 1950 by the USDA NRCS, this earth dam stands at a height of 12 feet and has a storage capacity of 500 acre-feet, serving the purpose of irrigation for the surrounding area. Situated on Beaver Creek, this structure is regulated by the DNRC and is inspected, permitted, and enforced by the state of Montana.

With a low hazard potential and a condition assessment of "Not Rated," David Drum #2 plays a crucial role in the water resource management of Phillips County. The dam has a spillway width of 660 feet and a maximum discharge capacity of 3,300 cubic feet per second, providing vital water supply for agricultural activities in the region. While the structure has not been modified in recent years, it continues to support the local community with reliable water resources.

As a part of the Omaha District under the USACE, David Drum #2 remains a key asset in the water infrastructure of Montana. With its historical significance dating back to the mid-20th century, this dam exemplifies the importance of private ownership in maintaining and managing water resources for irrigation purposes. Its location and design make it a valuable resource for climate enthusiasts and water resource professionals alike, showcasing the collaborative efforts of federal and state agencies in ensuring water security for 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.
