The dam, classified as an Earth type, stands at a height of 22 feet and stretches 420 feet in length, with a storage capacity of 450 acre-feet. Situated on Carlton Creek, the reservoir covers an area of 40 acres and serves the primary purpose of irrigation for the surrounding agricultural lands.
With a significant hazard potential and a moderate risk assessment level, Carlton Lake #1 is regulated by the Montana Department of Natural Resources Conservation (DNRC) and undergoes regular state inspections and enforcement measures. The spillway, classified as uncontrolled, is 28 feet wide, providing a vital safety feature for managing water levels during periods of high discharge. Despite its age, the dam's condition assessment remains unrated, prompting the need for ongoing monitoring and risk management measures to ensure its structural integrity and the safety of downstream communities.
As a historical irrigation structure, Carlton Lake #1 represents a key component of the local water resource infrastructure, playing a crucial role in supporting agricultural activities in the region. With its location in the picturesque city of Lolo and its association with the scenic Carlton Creek, the reservoir stands as a testament to the engineering ingenuity of its time, while also highlighting the importance of sustainable water management practices in the face of changing climate conditions.
