The Kettle River is a 175-mile-long river that flows through Minnesota's Pine and Carlton Counties, then crosses the border into northeastern Minnesota, where it flows through the St. Louis County, Itasca, and Koochiching Counties. The river was named after the Native American word "Gaa-zhiigwanaabikokaag" which means "river abundant with boiling kettles." The river has been used for logging, farming, and transportation in the past. Today, it is a popular spot for recreational activities such as fishing, boating, camping, and hiking. There are several reservoirs/dams, including the Sturgeon Lake Dam and the Big Falls Dam, that serve hydroelectric power and flood control purposes. The river is also used for agricultural irrigation.
