Summary
Built in 1950, this Earth dam stands at 25 feet high and spans 400 feet in length, with a normal storage capacity of 152 acre-feet. The reservoir serves primarily for recreational purposes, attracting enthusiasts to its tranquil waters that offer activities such as fishing and boating.
Situated on TR-BUTTE CREEK, the reservoir's low hazard potential and unassessed condition make it a relatively safe and stable structure. While it is not under federal ownership or funding, the state regulatory agency DNRC oversees its operations, inspections, and enforcement. Despite lacking in-depth assessments and emergency preparedness measures, Killenbeck Reservoir remains a picturesque spot within the Montana landscape, providing a valuable source of water for recreation and wildlife in the region.
For water resource and climate aficionados, Killenbeck Reservoir stands as a serene oasis in the heart of Montana, offering a glimpse into the intricate balance between human intervention and natural conservation. As climate change continues to impact water resources worldwide, the careful management and maintenance of reservoirs like Killenbeck become crucial for ensuring sustainable access to this vital resource for future generations. Its location in the Omaha District and under the jurisdiction of Congressional District 00, Montana, underscores its significance as a local and regional asset in the broader context of water resource management and climate adaptation efforts.

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.
