The St. Louis River estuary is considered one of the best places to find lake sturgeon in Minnesota. The estuary is located where the St. Louis River meets Lake Superior at Duluth. Lake sturgeon can be found in the estuary year-round, but they are most abundant in the spring and fall when they migrate to and from the lake to spawn.
Lake sturgeon are native to the Great Lakes and are considered a threatened species in Minnesota. They are long-lived fish that can grow up to 10 feet long and weigh over 300 pounds. Lake sturgeon feed on bottom-dwelling organisms such as clams, snails, and insect larvae.
The St. Louis River estuary provides an ideal habitat for lake sturgeon. The estuary is a shallow, warm body of water with a muddy bottom. There is abundant food for lake sturgeon in the estuary, and the water is well-oxygenated. The estuary is also relatively protected from predators, such as sea lampreys and walleye.
