The History<\/h2>\n

The connection between the Great Lakes and the Mississippi River is an important part of North American history. Once, the Great Lakes and Mississippi River were all part of the same river system that stretched from the St. Lawrence River in the east to the Gulf of Mexico in the south. However, a huge glacial lake formed as the glaciers receded, damming the Great Lakes and cutting off the Great lakes from the Mississippi River. This lake, known as Glacial Lake Agassiz, covered much of the northern portion of the United States, including the Great Lakes and Mississippi river watersheds.
\nAlthough the Great Lakes and the Mississippi River are no longer connected, the connection between them still affects both watersheds. As water from the Great Lakes flows into the Mississippi River watershed, it adds nutrients, which affects the water quality of the entire Mississippi River system. This has created a variety of challenges for communities that rely on either river system. <\/p>\n

The Research <\/h2>\n

A variety of scientific research has been conducted to explore the connections between the Great Lakes and the Mississippi River. One study by the University of Minnesota-Duluth looked at how the flow of water between the two watersheds affects water quality in both the Great Lakes and the Mississippi river. The study found that changes in the flow of water could significantly impact the water quality of both rivers.
\nIn a follow up study by the U.S. Geological Survey, researchers looked at how the amount of nutrients in the Mississippi River could be changed by adding nutrients from Great Lakes watersheds. The research indicated that the additional nutrients could potentially increase the nutrient load of the Mississippi River, leading to increased growth of algae and aquatic plants. However, the researchers also noted that more research is needed to understand the full impacts of the connection between the two watersheds. <\/p>\n

The Challenges <\/h2>\n

The connection between the Great Lakes and the Mississippi River can create a variety of challenges for those living near or relying on either river. Changes in water quality can affect the health of aquatic species, and can cause harm to humans if the water is not suitable for drinking or recreational use. Additionally, the nutrients from the Great Lakes can cause algae blooms in the Mississippi River, depleting oxygen levels and making the water unsuitable for aquatic species.
\nThe connection between the two rivers can also lead to the spread of invasive species. Zebra mussels and Asian carp, two species native to the Great Lakes, have been found in the Mississippi River and some tributary systems. Once these species become established, they can cause significant harm to local ecosystems. <\/p>\n

The Solutions <\/h2>\n

Communities along the two watersheds are working to address the challenges created by the connection between the Great Lakes and the Mississippi River. In many cases, local communities have implemented strategies to limit the amount of water flow between the two watersheds, as well as nutrient runoff. Additionally, many communities have implemented strategies to help prevent the spread of invasive species, such as Asian carp.
\nThe Great Lakes Commission, a binational organization aimed at protecting and restoring the Great Lakes, has also played a role in protecting the two watersheds. The commission works to coordinate efforts between the two watersheds to protect the water quality, as well as to reduce the spread of invasive species. <\/p>\n
