Course
The Wallace River begins at the divide between it and Salmon Creek. It flows west from here until it enters Wallace Falls State Park, where it flows southwest and drops over three large waterfalls, receives the North Fork Wallace River just below the final falls, before going in a westward direction again. It receives three large tributaries in short order before passing under the Stevens Pass Highway, Olney Creek, May Creek and Bear Creek. After flowing under the highway, it continues west until it reaches its confluence with the Skykomish. The North Fork Wallace River begins in Shaw Lake and flows south, passing through two more lakes, Jay Lake and Wallace Lake, before merging with the main fork just below the bottom of the three large waterfalls on the main fork. A trail leads to all three lakes.
