Spanning across 2,980,000km2, the Mississippi River flows through 40% of the United States. 3.766km long, one could think of it as North America’s “Amazon” River. The long body of water is a major contributor to our Country’s commerce. 90% of the nations agricultural exports flow through the river. In 2019 500Mln tons of goods from various industries were shipped on the river. The Mississippi River also serves as a water source and energy producer in the form of hydropower.

While above water is full of life, what’s underwater is a whole new world. Over 260 different species of fish can be found in the river making up a quarter of the countries total fish species. The river hosts popular sport fish like bass, pike, walleye, catfish, crappie, and panfish. What’s unique about the water is that several species of archaic fish can be found, the paddlefish & a couple species of sturgeon.

Surrounding area

The town of La Crosse, Wisconsin borders the river to the east. The college town see’s hosts a lot of people, from students to workers in the manufacturing industry. Boats can be seen everyday going down the river. The section of the river by La Crosse breaks off into swampy lakes, and mini winding rivers. The land between hosts several campgrounds, and parks.

Underwater landscape

Underwater, sand, silt, and mud are present. The slow current has gradually flattened out the river bottom. Rocks and boulders have been smoothed out over the years. The sections where the river sort of wanders off all have different variants of depth. A bridge running through the water creates a micro ecosystem. Along the river bank, plants and trees creep to the waters edge. Driftwood can be seen washed ashore floating down from north of the river.

Threats to ecology

The busy town creates its fair share of pollution. Both river and air quality are far from perfect. Over the last 20 years, river pollution was made a priority however, trash may still find its way in. Boats and water vehicles also leak oil and gas into the water. During periods of heavy rain, the river picks up speed and kicks up the sediment, changing the landscape below, and clogging up water ways. dams and dredges have been used to combat this problem.
