2024 Map of Grable Coulee

USGS Topo · Published 2024

About this map

Milk River valley bottomlands and the intricate irrigation systems of the Fort Belknap Canal define this portion of Blaine County. The landscape is marked by the sharp contrast between the managed water of the Thirtymile Reservoir and the deeply eroded drainage patterns of Grable Coulee and Harts Coulee. A network of rural routes, including Savoy Rd and Old Savoy Rd, connects the scattered agricultural holdings and follows the natural contours shaped by Thirtymile Creek and Wayne Creek. The presence of Grable Coulee Spring highlights the critical role of water sources in this semi-arid terrain, where irrigation infrastructure has historically transformed the river valley for local production.
