2014 Map of Thompson Lakes

About this map

Kootenai National Forest dominates this Northwest Montana landscape, where the interconnected waters of Upper Thompson Lake, Middle Thompson Lake, and Lower Thompson Lake form a chain along the corridor between Lincoln, Sanders, and Flathead counties. The drainage of the Thompson River and its various tributaries, including Tallulah Cr and Boiling Springs Cr, shapes the complex topography of the region. Rising above the lakes, Bowers Peak serves as a significant landmark in a terrain defined by high ridges and deep drainages like Barnum Cr. The map reveals a specialized local infrastructure, from the Campbell Ranch Airport in the southeast to a network of forest and access roads such as Middle Thompson Lake Rd and ACM Rd. This 2014 survey captures the balance between managed forest lands and the recreational waters that define the character of this part of the Cabinet Mountains region.
