The Saint Louis River (abbreviated St. Louis River) is a river in the U.S. states of Minnesota and Wisconsin that flows into Lake Superior. The largest U.S. river to flow into the lake, it is 192 miles (309 km) in length[1] and starts 13 miles (21 km) east of Hoyt Lakes, Minnesota. The river's watershed covers 3,634 square miles (9,410 km2). Near the Twin Ports of Duluth, Minnesota and Superior, Wisconsin, the river becomes a freshwater estuary.

According to Warren Upham, the Ojibwe name of the river is Gichigami-ziibi (Great-lake River). He notes:

"The river was probably so named by Pierre Gaultier de Varennes, sieur de La Vérendrye (1685–1749), who was a very active explorer, in the years 1731 and onward, of the vast country from Pigeon River and Rainy Lake to the Saskatchewan and Missouri Rivers, establishing trading posts and missions. The king of France in 1749, shortly before the death of La Vérendrye, conferred on him the cross of Saint Louis as a recognition of the importance of his discoveries, and thence the name of the Saint Louis River appears to have come. On Jean-Baptiste-Louis Franquelin's map (1688) and Philippe Buache's map (1754), it is called the Rivière du Fond du Lac, and the map by Gilles Robert de Vaugondy (1755) and Jonathan Carver's map (1778) are the earliest to give the present name."[citation needed]

The river was a vital link connecting the Mississippi River waterways to the west with the Great Lakes to the east. Jay Cooke State Park is located near the mouth of the river and is the site of a canoe portage used by Native Americans, European explorers, fur traders, Voyageurs, coureurs des bois, and missionaries of the 18th and 19th centuries. It was a rough trail of steep hills and swamps that began at the foot of the rapids above the neighborhood of Fond du Lac ("head of the lake") and climbed some 450 feet (140 m) to the present day city of Carlton. Above Carlton travelers proceeded upstream and continued on to Lake Vermillion and the Rainy River. Or they may have traveled southwest up the East Savanna River, portaged the grueling 6 mile long Savanna Portage (now a state park), and then paddled on to the Mississippi River.

By the mid 20th century, the lower Saint Louis River became one of the most heavily polluted waterways in the state. Holling Clancy Holling, in his 1941 book Paddle-to-the-Sea, illustrated the polluted state of the Saint Louis River. By 1975, the river became an Environmental Protection Agency Area of Concern. The Western Lake Superior Sanitary District (WLSSD) was established in 1971 to address serious pollution problems in the lower Saint Louis River Basin. WLSSD's regional wastewater treatment plant began operating in 1978. Within two years, fish populations rebounded and anglers began returning to the river. Through the 1980s and 1990s, additional cleanups took place, and the river is now significantly less polluted.

The river is fished for walleye, northern pike, smallmouth bass, largemouth bass, bluegill, black crappie, and channel catfish populations. Other species of rough fish include Shorthead Redhorse and White Sucker. Attempts to introduce sturgeon are under way; sturgeon, if caught, are to be returned. The river is frequented by those traveling the Minnesota DNR Saint Louis River Water Trail,[2] which has campsites and angling.

The Saint Louis River Trail Association [3] is planning construction of a long-distance hiking trail along more than half the length of the river. Construction of the first 36-mile segment began in early 2012, with cooperation from the Minnesota DNR; the trail association hopes to have this section completed in 2015.

Saint Louis River AOC[edit]

The Saint Louis River was listed in 1987 as an "Area of Concern" by the Great Lakes Water Quality Agreement 1987 Ammendment. Nine of 14 Beneficial Use Impairments (BUIs) were identified in the Saint Louis River AOC. The AOC designation has led to the Remedial Action Plan (RAP) process outlined in the GLWQA. The most recent update is the 2013 RAP Update: A Roadmap to Delisting and can be found on the WI Department of Natural Resources (WI DNR) and Minnesota Pollution Control Agency (MPCA) webpages listed below. This document outlines the BUI removal strategies and list of actions to delist the Saint Louis River as an AOC by 2025.
