Summary
Built in 1969 for irrigation purposes, this dam stands at a height of 30 feet with a length of 1320 feet, providing a storage capacity of 244 acre-feet. Despite being categorized as low hazard potential, the dam's condition assessment is currently listed as "Not Rated," signaling a need for further inspection and evaluation.
Managed by the Montana Department of Natural Resources and Conservation (DNRC), K and L Mc Dowell #3 is subject to state regulation, permitting, inspection, and enforcement. Although the dam has not been modified in recent years and lacks detailed data on its drainage area and maximum discharge capacity, its primary purpose of irrigation remains critical for the surrounding agricultural community. As an important water resource structure in the region, the dam's safety and maintenance are essential to ensure reliable water supply for irrigation and other uses.
While K and L Mc Dowell #3's emergency action plan (EAP) status and risk assessment details are currently undisclosed, its geographic coordinates and historical completion date provide valuable information for water resource and climate enthusiasts. As part of the Omaha District under Congressional District 00 of Montana, this dam plays a vital role in supporting the local economy and environment. Moving forward, continued monitoring and assessment of K and L Mc Dowell #3 will be crucial to safeguarding its integrity and functionality for future water management needs.

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.
