2024 Map of North Chinook Reservoir

About this map

North Chinook Reservoir serves as the central anchor of this northern Montana landscape, reflecting the essential role of water management in Blaine County's high plains. The map illustrates a complex network of natural drainages and irrigation infrastructure, notably the North Chinook Irrigation Canal which diverts water to support local agriculture. The terrain is defined by a series of named coulees, including Corregan Coulee, Burrell Coulee, and Scotchmans Coulee, which channel runoff toward Battle Creek and its tributary, East Fork Battle Creek. These landforms reveal the erosional patterns of the region and dictate the placement of local roads like Anita Rd and Norweigain Rd. The surveyor's grid, marked by sections such as t36n r18e and t35n r19e, shows the organized division of this expansive ranching and farming territory.
