2020 Map of Gilman

About this map

Gilman lies on the western edge of this prairie landscape, where the agriculture of the Sun River valley relies on a sophisticated network of early twentieth-century irrigation infrastructure. The map documents the extensive reach of the Sun River Slope Canal and the Floweree Canal, which divert water across the plains through complex channels like the Lytle Clemons Ditch and Bickle Burke Ditch. These man-made features work in tandem with the natural drainages of School Section Coulee and Clemons Coulee, illustrating the critical role of water management in the development of the Montana frontier. To the east, the terrain rises toward Gilman Hill and Meyer Hill, overlooking the Sun River as it winds through the heart of the township. Local landmarks such as Meyer Lake and Basin Lake punctuate the grid of rural roads, offering clear reference points for those tracing family land holdings or early homestead footprints in this section of Lewis and Clark County.
