Summary
The reservoir, completed in 1930, has a dam height of 10 feet and a storage capacity of 62 acre-feet, with a normal storage of 32 acre-feet. Situated on the West Fork Flat Creek, the reservoir is regulated by the Montana Department of Natural Resources and Conservation (DNRC) and is inspected regularly to ensure its safety and compliance with state regulations.
Although Leveque Reservoir has a low hazard potential, it has not been rated for its condition assessment. The reservoir's emergency action plan (EAP) status and risk assessment measures are currently unreported, highlighting the need for further evaluation and preparedness. With its primary purpose being water supply for fire protection and livestock, the reservoir plays a crucial role in supporting local agriculture and protecting the surrounding community from potential fire hazards.
As a key water resource in the area, Leveque Reservoir serves as a valuable asset for the residents of ULM and the broader Cascade County. Its location, operational history, and storage capacity make it a vital component of the region's water infrastructure, emphasizing the importance of ongoing maintenance and regulatory oversight to ensure its continued functionality and safety for years to come.

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.
