2020 Map of McKinnsey Reservoir East

About this map

McKinnsey Reservoir and a network of seasonal watercourses define this high plains landscape in Hill County. The terrain is characterized by the distinct erosional patterns of drainage features such as Tommy Allen Coulee and Schultz Coulee in the northwest, which carve into the surrounding plateau. Further east, Ninemile Coulee marks the edge of the survey area, illustrating the characteristic drainage systems that define this part of the northern Montana prairie. These coulees, named for early figures or local landmarks, offer a detailed view of the water management and natural hydrology essential to life in this arid region, providing a clear record of the area's physical geography for local historians and researchers.
