Summary

Built in 1936 by the USDA NRCS, this earth dam stands at 10 feet high and spans 500 feet in length, with a storage capacity of 147 acre-feet. The dam serves the primary purpose of irrigation, helping to support agricultural activities in the area.

Managed by the Montana Department of Natural Resources and Conservation (DNRC), Bergstrom's Farms #2 is regulated, inspected, and enforced by the state to ensure its safe operation. With a low hazard potential and a condition assessment of "Not Rated," the dam provides essential water resources for the surrounding community while posing minimal risks to downstream areas. Its location in Loma, Montana, makes it a vital infrastructure for water management in the region.

As a key component of the water resource network in the area, Bergstrom's Farms #2 plays a crucial role in supporting agricultural productivity and sustainable water use. With its historical significance dating back to the 1930s, the dam continues to contribute to the local economy and ecosystem by providing reliable irrigation water for farmers. The collaborative efforts of the USDA NRCS, DNRC, and other state agencies ensure the safe and efficient operation of this essential water infrastructure.

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.
