2020 Map of Johnson Lake

About this map

Big Muddy Creek meanders through the northwest corner of this Roosevelt County landscape, defining a wide, marshy basin that includes Johnson Lake and Homestead Lake. The terrain transitions from these low-lying wetlands into the higher, dissected plateaus of the Missouri Coteau, where intermittent drainages like Sheep Cr and Sand Cr have carved intricate coulees into the prairie. The map shows a strictly gridded section-line road system characteristic of the High Plains, with local routes such as W Froid Rd and Stab Rd providing access to remote ranching and agricultural tracts. This 2020 survey documents the intersection of t30n r55e and t29n r55e, capturing a sparsely populated corner of northeastern Montana where water remains the primary driver of the land's utility and character.
