Gilman lies at the heart of this agrarian landscape in Lewis and Clark County, where the plains meet an intricate network of irrigation infrastructure and seasonal watercourses. The local hydrology is defined by the Sun River and its accompanying engineering works, including the Sun River Slope Canal, Floweree Canal, and Lytle Clemons Ditch, which redirect water across the drainage basins. These systems support the surrounding ranchlands and small-scale agriculture characteristic of this part of Montana.
