2017 Map of Berkholder Reservoir

About this map

The Toole and Liberty County line divides this stretch of Montana ranchland, where water management is central to the landscape. The Berkholder Reservoir sits as a primary collection point for the drainage of local coulees, including Steep Coulee and Price Coulee. To the south, the Big Dam further regulates the seasonal flow through this arid prairie. The map details a network of named drainages that defined property and transit in the early 21st century, from Alkali Coulee in the northwest to Kinyon Coulee in the northeast.
