Summary
The dam stands at a height of 30 feet and has a storage capacity of 38 acre-feet, with a normal storage level of 26 acre-feet. Situated along TR-Buckley Coulee, this structure plays a crucial role in safeguarding the area against potential hazards, with a low hazard potential rating.
Managed by the Montana Department of Natural Resources and Conservation (DNRC), Hillkleberry Coulee is subject to state regulation, inspection, and enforcement to ensure its safety and functionality. While the dam's condition assessment is currently not rated, its emergency action plan status, risk assessment, and inundation maps are yet to be determined. Despite its modest size, its significance in providing essential water resources for fire protection and livestock highlights the importance of maintaining and monitoring this structure.
Located in Congressional District 00 of Montana, Hillkleberry Coulee serves as a vital water resource in the region, contributing to the local ecosystem and agricultural practices. With its strategic positioning and purposeful design, this dam reflects a blend of functionality and environmental stewardship, catering to the needs of the community while adhering to state regulatory standards. For water resource and climate enthusiasts, Hillkleberry Coulee offers a fascinating glimpse into the intersection of infrastructure development, natural resource management, and climate resilience in the American West.

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.
