On its way from Minnesota to Louisiana, the Mississippi River passes through ten states and connects 14 known lakes. Wisconsin, Illinois, Kentucky, Tennessee, and Mississippi are located on the east side of the Mississippi River, whereas Iowa, Missouri, and Arkansas are located on the west. Here, we’ll take a closer look at each of the lakes that connect to this river system.

Glacial Lake Agassiz is a lake basin in central North America. Its area is larger than all the contemporary Great Lakes combined.  This glacial lake basin has many lakes. The most famous are Lake Winnipeg, Lake Manitoba, and Lake Winnipegosis. Lake Dauphin, south of Lake Winnipegosis, and Lake St. Martin, on the Fairford or Little Saskatchewan River, the exit of Lakes Manitoba and Winnipegosis, are tributaries to these larger lakes.

The 52-mile Agassiz Recreational Trail is located close to the North Dakota border and offers stunning vistas of the Sand Hill and Wild Rice rivers. Alternating between woodland areas and beautiful farmland, the walk follows an abandoned railroad grade.

2. Baldwin Lake (Anoka County, Minnesota)

Anoka County, Minnesota, United States, is home to Baldwin Lake, a lake located less than a mile from Circle Pines. Fishers can catch crappie, striped bass, bullheads, largemouth bass, and black bullheads in this area, among other species.

Lake Bemidji is a glacially created lake in northern Minnesota, USA. It collects and drains the Mississippi, which is less than 50 miles (80 km) downstream. Lake Beltrami is in southern Beltrami County, near Bemidji on its western bank. Lakes Bemidji and Irving were said to have been constructed in Paul Bunyan’s footprint due to their shape. The Ojibwe called the lake “Traversing Lake” because it traverses the Mississippi River.

Lake Bemidji is a renowned tourist destination. The lake offers fishing, boating, swimming, water skiing, tubing, and hiking. North of it is Lake Bemidji State Park. The north trailhead of the Paul Bunyan State Path connects to 16.6 miles of paved trail along the lakeshore. Diamond Point Park, Cameron Park, Library Park, and South Shore Park are among the largest parks in Bemidji. Two resorts, a bed & breakfast, a campground, and many hotels dot the lake’s south side development.

4. Lake Beulah (Arkansas–Mississippi)

Lake Beulah is an 812-acre lake in Walworth County, Wisconsin.


Lake Beulah is an 812-acre lake in Walworth County, Wisconsin. It is an oxbow lake in Bolivar and Desha counties in Mississippi and Arkansas. The Arkansas-Mississippi border follows the lake’s arc. Beulah Bend’s oxbow lake formed when it was cut off from the Mississippi’s main flow. The Napoleon Channel made river transportation more direct, but due to floods in 1868 and 1874, part of the town was permanently submerged, and by 1882, it was no longer visible on river charts. The community of Beulah, Mississippi, has a public boat launch on the east shore. The lake’s water is semi-clear.

Types of Fish:

  • Bowfin
  • Crappie

Onalaska, Wisconsin, is home to the 7,688-acre (31.11-square-mile) Onalaska Lake. Its highest point is 633 feet above sea level, while its deepest point is 43 feet below.

Upper Mississippi’s Lake Onalaska is a year-round draw for tourists. From waterskiing and boating to fishing and beach picnics, summer tourists can partake in a wide range of recreational activities.

11. Lake Pepin

Lake Pepin, a natural body of water straddling the state line between Minnesota and Wisconsin, is the largest lake formed by the Mississippi River. A massive glacial lake carved out a valley here during the end of the Ice Age. The Mississippi River, a glacial successor, created the lake by expanding out across the original valley and partially blocking it. This popular lake now has boat, car, and train traffic. One of the largest freshwater lakes in the US, Lake Pepin is 21 feet deep and 2 miles wide. The current St. Croix River basin in Minnesota was formed by the glacial rivers Warren and Duluth, which drained during the last Ice Age. These two glacial rivers shaped this lake.

Lake Pepin is a 30,000-acre natural enlargement that boasts magnificent bluffs surrounding a natural lake. Its profusion of plant and animal life acts as a large water filter, reducing silt and other contaminants. The lake has inspired many famous authors and painters, as well as the millions of tourists who visit each year. This lake is one of the Midwest’s most popular natural playgrounds for leisure and sporting activities. Its cities include Maiden Rock, Reads Landing, Stockholm, and Lake City.

12. Lake Whittington

Lake Whittington is an oxbow lake in Bolivar and Desha counties in Mississippi and Arkansas. The Arkansas-Mississippi boundary runs through the lake’s middle. The Mississippi River used to flow north-south, curving east into Mississippi. A narrow waterway connects the lake to the Mississippi. Bypassing the river, this route allows spawning fish to enter Lake Whittington. The canal also causes seasonal fluctuations in the Mississippi River’s water level. In the fall, when the Mississippi River’s water levels are normally lowest, Lake Whittington may be totally blocked off from the river, forming three pools of water.

Largemouth Bass Virus (LMBV) has been found in the lake; therefore, fish should not be transferred from this lake! If you plan to fish the water, make sure to clean any used live wells with bleach after. LMBV is not known to infect humans. In the lake are bluegill, catfish, flathead, gar, largemouth bass, minnows, silversides, white bass, and yellow bass. The main aquatic plant is duckweed. Although an Arkansas or Mississippi fishing license is required to fish the lake, all cars and most recreational boats must enter from Mississippi.

13. Lake Winneshiek

Numerous paths for hiking and biking may be found along the 141 kilometers of shoreline that surround the lake. Hunting prospects are abundant in the neighboring forest, where there are a lot of trees and wildlife.
