1983 Map of Todd Lakes

About this map

The Todd Lakes define this section of Valley County, where the plains are etched by an intricate network of drainage channels. This 1983 provisional survey highlights the confluence of Wolf Creek and its many tributaries, illustrating the water-management and cattle-grazing landscape of the Fort Peck Indian Reservation. Significant drainage features like Thiessen Coulee and Tree Coulee cut through the terrain, joining the West Fork and Dry Fork Wolf Creek as they flow toward larger basins. The map captures the area as it was recorded during late-1970s field checks, showcasing a sparsely populated ranching environment where the movement of water across the northern Montana prairie dictates the layout of the few unimproved roads and property boundaries.
