Summary
Completed in 1952, this irrigation structure stands at a height of 16 feet and has a maximum storage capacity of 54 acre-feet. With a low hazard potential and a "Not Rated" condition assessment, Killen #3 serves its primary purpose of irrigation for the surrounding agricultural lands.
Managed by the Montana Department of Natural Resources and Conservation (DNRC), Killen #3 is subject to state regulations, permitting, inspection, and enforcement to ensure its safe operation. Despite not being rated for its condition, the dam continues to provide essential water resources for the local community. Its location in Rosebud County, Montana, makes it a vital component of the regional water infrastructure, contributing to the sustainability of water resources in the area.
As an integral part of the water management system in Montana, Killen #3 plays a crucial role in the irrigation and agricultural activities in Kinsey. With its strategic positioning along the Spring Coulee river and a history dating back to the 1950s, this dam exemplifies the importance of sustainable water resource management in the face of changing climate conditions. Enthusiasts of water resources and climate resilience will find Killen #3 to be a fascinating example of how infrastructure can adapt and evolve to meet the challenges posed by a changing environment.

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.
