Apple River in Apple River Canyon State Park

Apple River

Stockton, Illinois, United States

Site is located in Apple River Canyon State Park just after the confluence of the North and South forks of the Apple River. Sampling location is on the southwest bank in the central park space, and is easily accessible. Water flows rapidly, and some ice is often present in winter, thought it rarely freezes over.
