Summary
Completed in 1958, this earthen dam stands at a height of 21 feet and has a primary purpose of providing fire protection, stock water, and serving as a small fish pond. With a storage capacity of 490 acre-feet, Knudson serves as a crucial water resource for the surrounding area.
Managed by the Montana Department of Natural Resources and Conservation (DNRC), Knudson has been deemed to have a low hazard potential and is currently rated as "Not Rated" in terms of its condition assessment. Despite not having a designated inspection frequency or a detailed risk assessment, the dam is equipped with emergency action plans to ensure preparedness in case of any unforeseen events. The surrounding community can rest assured that Knudson is well-regulated and maintained in accordance with state permitting, inspection, and enforcement standards.
Knudson serves as a vital component of the local water infrastructure, providing essential services such as fire protection and stock water while also enhancing the natural habitat with a small fish pond. With its relatively low hazard potential and state-regulated status, this dam stands as a testament to responsible water resource management in Montana. Its strategic location along the Gold Gulch river underscores its importance in sustaining the surrounding ecosystem and supporting the community's needs for water resources and climate resilience.

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.
