Summary

Completed in 1963, this dam serves multiple purposes including fire protection, stock watering, and creating a small fish pond. With a height of 20 feet and a storage capacity of 67 acre-feet, Kjeldgaard #2 plays a crucial role in managing water resources in the area.

The dam is regulated by the Montana Department of Natural Resources and Conservation (DNRC) and is considered to have low hazard potential. While its condition assessment is currently not rated, Kjeldgaard #2 has undergone regular inspections, with state jurisdiction, permitting, and enforcement in place to ensure its safety and functionality. Located on TR-FLY CREEK, this dam contributes to the overall water management efforts in the region.

As a key element in the local water infrastructure, Kjeldgaard #2 provides valuable benefits for both the environment and the community it serves. With its primary purpose being fire protection and water supply, this earth dam exemplifies the importance of sustainable water resource management in mitigating climate-related risks and enhancing resilience in the face of changing environmental conditions.

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.
