2011 Map of Irwin

About this map

The settlement of Irwin and its surrounding ranchlands define this corner of the High Plains near the Nebraska-South Dakota border. This landscape is characterized by a high density of alkali basins and small perennial water bodies, including Alkali Lake, North Twin Lake, and South Twin Lake. The presence of several named family operations, such as McGinley Ranch, Wiley Ranch, and Hathorn Ranch, underscores the area's long-standing reliance on cattle ranching and hay production. Significant water management efforts are visible in the long transit of the Horseshoe Drainage Ditch, which cuts across the central terrain. Low-lying hay ground is noted at Scott Meadow and Slim Meadow, while the local road network is centered on Irwin Rd, connecting the scattered ranch houses to the regional center.
