2024 Map of Austin Lake

About this map

Austin Lake sits at the heart of this high plains landscape in Phillips County, defining a region characterized by its drainage patterns and intermittent water sources. The terrain is deeply inscribed by several distinct coulees, including Lush Coulee, Martins Coulee, and Butte Coulee, which channel seasonal runoff through the undulating prairie. Human presence is marked primarily by ranching infrastructure and a network of remote roads such as Whitewater Rd and Loring Cutacross Rd. Managed water resources like Adair Reservoir and Plum Reservoir, along with the natural Austin Spring, highlight the critical importance of water management in this arid northern Montana environment. The map provides a clear look at the Public Land Survey System grid, illustrating the large-scale township and range divisions that dictate the modern land use and boundaries of this expansive territory.
