The Apple River is a tributary of the St. Croix River, about 70 mi (113 km) long, in northwestern Wisconsin in the United States. Via the St. Croix, it is part of the watershed of the Mississippi River.
It issues from Staples Lake in Barron County and flows generally southwestwardly through Polk and St. Croix Counties, through several lakes and past the City of Amery Somerset. It joins the St. Croix River 7 mi (11.3 km) northeast of Stillwater, Minnesota and the village of Star Prairie.
In the Ojibwe language, the Apple River is called Waabizipinikaan-ziibi, meaning "River Abundant with Swan Potatoes". This name was translated into French, but only pomme (apple) of the French word for "potato" (pomme de terre - apple from the earth) was translated into English.
The Apple River was once an important route of trade for the logging industry; timber was floated downstream from logging camps in the north to a sawmill in Amery, Wisconsin where it was cut, loaded onto trains and transported throughout the region. Today, the river generates tourism revenue through recreation and resorts. Its relatively gentle rapids make it very popular for canoeing, tubing, camping, concerts, and is a popular fishing spot through all seasons. Tubing involves floating on a river on top of an inner tube.
Canoeing on the Apple River just got easier in with the installation of the new Canoe and Kayak portage around the Amery Dam that was install June of 2010. There is a dock to use to on the north side of the dam and the easy access portage is located east of the Amery Dam on the other side. If you want to enjoy a picnic before you continue on your journey there are several picnic tables to have a relaxing lunch or dinner.
