2024 Map of Potato Lakes

About this map

The John Long Mountains and Sapphire Mountains dominate this high-country landscape in Granite County, where the Deerlodge National Forest encompasses vast stretches of timbered terrain. Water management is central to the area's layout, evidenced by the Flint Creek Canal and the Carey Lateral diverting flows across the Philipsburg Valley. Numerous small water bodies, notably the Potato Lakes, are scattered throughout the western sections, while the East Fork Reservoir sits at the base of the Anaconda Range in the southeast corner.
