2020 Map of Berkholder Reservoir

About this map

Berkholder Reservoir and the Big Dam anchor this high plains landscape along the border of Liberty and Toole Counties. The terrain is defined by a dense network of coulees that drain the territory, including the family-named Grandma Coulee, Reeve Coulee, and Fernell Coulee. These drainage patterns dictate the sparse road network, where routes like Galata Rd and Gus Blaze Rd navigate the undulating topography. At the site of Kinyon, the map shows a junction of local roads in a region traditionally dominated by ranching and dryland agriculture. The presence of the Big Dam suggests the vital importance of water management in this northern Montana environment, providing a focal point for local geography and history.
