Summary
This dam on Rocky Coulee serves multiple purposes, including fire protection, stock watering, and creating a small fish pond. With a dam height of 10 feet and a length of 500 feet, it has a storage capacity of 211 acre-feet and a drainage area of 47.5 acres. The dam has a low hazard potential and is currently not rated for its condition.
Managed by the Montana Department of Natural Resources Conservation (DNRC), Bergstrom's Farms dam is equipped with state-regulated inspection, permitting, and enforcement processes to ensure its safety and functionality. The dam is located in Congressional District 00, Montana, under the jurisdiction of the state regulatory agency. Although the dam's condition is not rated, it meets state guidelines for emergency action preparedness, with contact information updated and an emergency action plan in place.
For water resource and climate enthusiasts, Bergstrom's Farms presents an interesting case study of a historic earth dam serving multiple purposes in a rural agricultural setting. With its location in the picturesque county of Pondera, Montana, and its proximity to the Omaha District of the USACE, the dam showcases the vital role of water management infrastructure in supporting agricultural activities and wildlife conservation efforts in the region.

Dam Data Reference
Condition Assessment
SatisfactoryNo 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
HighDams 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.
