Summary
The dam, completed in 1940, stands at a height of 30 feet and has a storage capacity of 111 acre-feet. It serves the primary purpose of irrigation and is regulated by the Montana Department of Natural Resources and Conservation (DNRC).
Despite being classified as a low hazard potential structure, Wm Knight #1 has not been rated for its condition assessment. The dam has not been inspected in recent years, and there is limited information available regarding its emergency action plan or risk assessment. It is essential for water resource and climate enthusiasts to monitor the condition and regulatory compliance of such structures to ensure public safety and environmental conservation in the face of changing weather patterns and water availability.
As a critical component of the irrigation infrastructure in the region, Wm Knight #1 plays a vital role in supporting agricultural activities and water resource management. However, the lack of recent inspections and condition assessments raises concerns about the overall safety and resilience of the dam in the face of potential climate-related challenges. Stay tuned for updates on the regulatory oversight and maintenance of Wm Knight #1 to ensure the sustainable and efficient use of water resources in the area.

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.
