2011 Map of Geddart Lake

About this map

The Poplar River meanders through this portion of Roosevelt County, Montana, carving a complex riparian corridor across the plains. This landscape is defined by its water management and early 21st-century ranching infrastructure, featuring the Graninger Dam and the namesake Geddart Lake. Local land use is centered around family-named locations such as Kirns Ranch, situated near the rugged breaks of Kirns Coulee. The map also captures the vast drainage patterns of the high plains, with Slims Coulee in the south and a network of rural routes like Froid Hwy and Empire Bridge Rd that connect these remote homesteads. The lack of dense settlement emphasizes the area's agricultural character, where life follows the path of the river and the reach of the local coulees.
