Summary
Standing at a height of 14 feet with a length of 660 feet, the dam has a storage capacity of 151 acre-feet and serves as a vital water resource for the area. Despite its low hazard potential, the dam is regulated by the Montana Department of Natural Resources and Conservation (DNRC) and undergoes regular inspections to ensure its safety and functionality.
The dam, with its primary purpose being irrigation, plays a crucial role in sustaining agriculture in the region by providing water for crops and livestock. It is situated in a picturesque location, surrounded by the natural beauty of Montana, making it a significant landmark in the area. While the dam's condition is currently rated as "Not Rated," efforts are made to ensure that it meets all regulatory standards and guidelines to prevent any potential risks or hazards associated with its operation.
As a part of the Omaha District and under the jurisdiction of the state of Montana, Knight Dam stands as a testament to the importance of water resource management in sustaining agricultural activities in the region. With its historical significance dating back to 1936, the dam continues to serve as a vital infrastructure for irrigation and water storage, demonstrating the intersection of human engineering with the natural environment to support the needs of the local community.

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.
