2011 Map of Austin Coulee

About this map

Austin Coulee defines the drainage patterns of this Phillips County landscape, where water management is central to the land's utility. The 2011 survey reveals a territory marked by localized irrigation and stock water structures, specifically Morrison Dam in the north and the E Wasson Number 2 Dam to the east. These man-made features work in tandem with natural waterways like Little Cottonwood Creek to manage the intermittent flows common to the Montana plains. Transportation across this expanse is anchored by HWY 242, which provides the primary north-south transit corridor through an area otherwise characterized by its isolation and its reliance on the complex network of coulees and seasonal stream beds.
