Question: Which states in the United States of America have connections to both the Saint Louis River and Lake Superior?

Context paragraphs:
Embarrass River (Minnesota): The Embarrass River is a 50.5 mi tributary of the Saint Louis River in northern Minnesota, United States.  It rises just west of the city of Babbitt and flows southwest, turning briefly south to thread a gap between the Embarrass Mountains to the east and the Mesabi Range to the west.  The river flows into the Saint Louis River southeast of Eveleth.  During the fur-trading days and the era of exploration, the river was part of a historic trade route from Lower Canada via Lake Superior, across the Height of Land, and down the Rainy River to Lake Winnipeg to the "pays d'en haut"—the fur-bearing regions of the Canadian northwest.

West Swan River: The West Swan River is a 42.2 mi tributary of the East Swan River of Minnesota, flowing to the Saint Louis River and eventually Lake Superior.  The West Swan River flows into and out of Snowshoe Lake and Kelly Lake west of Hibbing.  Presently there are problems with flowage, due to obstructions in the river.  The mines that have polluted the river have left it facing severe problems.

Lake Superior: Lake Superior is the largest of the Great Lakes of North America.  The lake is shared by the Canadian province of Ontario to the north, the US state of Minnesota to the west, and Wisconsin and the Upper Peninsula of Michigan to the south.  It is generally considered the largest freshwater lake in the world by surface area.  It is the world's third-largest freshwater lake by volume and the largest by volume in North America.  The furthest north and west of the Great Lakes chain, Superior has the highest elevation and drains into the St. Mary's River.

Saint Louis River: 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 mi in length and starts 13 mi east of Hoyt Lakes, Minnesota.  The river's watershed covers 3634 sqmi .  Near the Twin Ports of Duluth, Minnesota and Superior, Wisconsin, the river becomes a freshwater estuary.

Superior Bay: Superior Bay is a narrow inlet of Lake Superior along the border of Minnesota and Wisconsin.  It is 7 miles long and 0.5 miles wide.  A small strait connects it to the Saint Louis Bay to the west, into which the Saint Louis River empties.  Superior Bay is located between the city of Superior and the Park Point neighborhood of Duluth.  The Duluth Harbor Basin is nearby.

Fond du Lac Indian Reservation: The Fond du Lac Indian Reservation (or Nah-Gah-Chi-Wa-Nong ("Nagaajiwanaang" in the Double Vowel orthography), meaning "Where the current is blocked" in the Ojibwe language) is an Indian reservation in northern Minnesota near Cloquet in Carlton and Saint Louis counties.  Off-reservation holdings are located across the state in Douglas County, in the northwest corner of Wisconsin.  The total land area of these tribal lands is 153.8375 sqmi .  It is the land-base for the Fond du Lac Band of Lake Superior Chippewa.  Before the establishment of this reservation, the Fond du Lac Band of Lake Superior Chippewa were located at the head of Lake Superior, closer to the mouth of the Saint Louis River, where Duluth has developed.

East Two River: The East Two River is a 25.0 mi tributary of the Saint Louis River in northern Minnesota, United States.  It rises at the outlet of Silver Lake in the city of Virginia and flows southwest, joining the Saint Louis River in McDavitt Township, just upstream of the outlet of the West Two River.

Midway River: The Midway River is an 18.8 mi river located in southern Saint Louis County and northeast Carlton County, Minnesota, United States.  It is a tributary of the Saint Louis River and flows northeast to southwest.  The Midway River rises in the central part of Hermantown, then flows through Midway Township and Thomson Township, before flowing into the Saint Louis River southeast of Cloquet.

Point Douglas to Superior Military Road: Point Douglas to Superior Military Road, also known as Point Douglas to St. Louis River Military Road and as Douglas Highway, was a road that ran between Point Douglas, located at the outlet of the Lower St. Croix Lake near Hastings, Minnesota, first to the falls of the St. Louis River near Thomson, Minnesota, and later extended to the mouth of the St. Louis River in Superior, Wisconsin.  From Douglas Point immediately east of Hastings, Minnesota, the route connected Stillwater, Taylors Falls, Sunrise, Chengwatana, Fortuna, Scotts Corner, to Thomson and Superior.  Several discontinuous sections of this road are still in use.

Savanna Portage State Park: Savanna Portage State Park is a state park of Minnesota, USA, established in 1961 to preserve the historic Savanna Portage, a difficult 6 mi trail connecting the watersheds of the Mississippi River and Lake Superior.  The park contains a drainage divide separating the West Savanna River, which drains to the Mississippi River and the Gulf of Mexico, from the East Savanna River, which flows in an opposite direction to the Saint Louis River, Lake Superior and the Great Lakes, and the Saint Lawrence River to the Atlantic Ocean.
