Saint Louis River

Saint Louis River drainage basin

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 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.”

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, but the river remains polluted. In 2013 the State of Minnesota abruptly pulled out of a project intended to research the mercury problem in the river. The cooperating agencies including Wisconsin DNR and the Fond du Lac Tribe were not in agreement with the ending of the study. The level of mercury is so high that strong limitations on consumption of the fish are in effect by the Minnesota Department of Health which for example limit consumption of walleye for a 50 pound child to 1/6 of a pound per month or no more than one pound every six months.

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, which has campsites and angling.

The Saint Louis River Trail Association  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.
