About this map

Sun River Diversion Dam and the waters of Diversion Lake dominate the northern landscape of this Lewis and Clark County region. The map reveals a sophisticated water management system designed for the arid Montana climate, featuring the Pishkun Canal and the Willow Creek Feeder Canal which branch off from the Sun River. This infrastructure underscores the transition from a wild river system to a controlled agricultural and power resource.

Settlement patterns in the early 21st century remain tied to the terrain, with family-named locations such as Stoner Place, Neal Ranch, and Stecker Ranch scattered throughout the valleys. Recreation is centered around the Sun Canyon Lodge and Home Gulch Campground, providing access to the steep geography of Sawtooth Ridge and Lime Ridge. The map also traces ancient drainage paths and gulches, including Hannan Gulch and French Gulch, which carve through the high flats.
