This week we are beginning our full Length Mississippi series, and also we will team ago up through Mike Link and Kate Crowley. Link and also Crowley highlighted piece of their full Circle exceptional journey with the lifwynnfoundation.org Scientists’ Blog last year through a series of posts, the first of i beg your pardon you have the right to read here. They are beginning on a new adventure and commitment to the concern of new water: a trip up and also down the Mississippi River. They also are committed to sharing your observations and science with lifwynnfoundation.org schools.
You are watching: Does the mississippi river connect to the great lakes
The good Lakes room separated indigenous the Mississippi flow by six miles! The Mississippi river (also well-known as the great River) collects water native 31 states and 2 districts on that 2350 mile course from Lake Itasca come the Gulf the Mexico. It was the incentive for many explorations; famous explorers choose LaSalle, DeSoto, Joliet, Radisson, Hennepin, Marquette, Nicollet, Zebulon Pike, and Schoolcraft labored to discover new lands in an undiscovered world. Their explorations took them transparent the Mississippi flow Basin; the river getting to its resource at a town along the financial institutions of Lake Itasca.
A map that the place of Lake Itasca and the Mississippi River, and also its watershed. Native The university of Minnesota.
The Mississippi flow is 3782 km (2350 miles) long and averages 1.6 km (1 mile) wide, make a surface ar area that 6086.5 square kilometers (2,350 square miles) while Lake Superior has a 2494.5 kilometer (1550 mile) shoreline and also 82,102.6 square kilometers (31,700 square miles) of surface ar area. Lake Superior’s shore is divided in between three states and one Canadian province while the Mississippi River has 10 claims that re-superstructure its shore. But much more impressive than the surface area the the 2 water bodies is to compare the 2 watersheds. A watershed, additionally known as a catchment basin, is a huge area where rain, rivers and also other flow water bodies, and runoff circulation towards a single body that water (for example, one ocean). For Lake premium the watershed is just 127,686 square kilometers (49,300 square miles) – making an 82:128 proportion of water come watershed; a ratio of around 1.5 come 1. The Mississippi flow drains 3,108,000 square kilometers (1,200,000 square miles) – a ratio of 6.1:3,108 or 510 to 1. The Mississippi flow watershed has 31 states and also 2 Canadian Provinces.
Lake Itasca is the i agree upon source (some wanted to think about Elk Lake and also its small outflow come Itasca to it is in the source, and others said Nicollet Lake and also its small boggy stream is the real headwaters) due to the ruling of the Minnesota government. The is an inspiring place with forests of large, old red and also white pines and also a picturesque beginning to the flow that reflects our human being influence – originally the river just ran out of the boggy landscape in ~ the north end of the lake, yet rocks were put in place and also a channel designated to come to be the official start. Millions have actually walked this rocks thinking that the is a herbal spot and also loving the idea of stepping in the water together it leaves for the rendezvous through the Gulf of Mexico.

With this geographic landscape in mind we started to think that Minnesota as a distributary – a place which outsources that is water come the an excellent Lakes and also the Gulf, and also in fact to Hudson Bay and the Arctic through the northern flow of the Red flow on the Minnesota and also North Dakota border. We receive it in pure type and climate it begins to relocate on, however what happens together it moves is the problem. Lake Superior has actually its long axis on one East/West bearing for this reason the human being who re-superstructure the waters also experience similar climate.
Unfortunately, rivers have been believed of as places to eliminate waste – every kinds of rubbish – due to the fact that the water naturally takes the materials downstream. Those that live upstream are much more ignorant come the issue, but an ext people live downstream and have only a limited amount of source to usage as pesticides, herbicides, fertilizers, lawn and also road runoff, petroleum products, invasive species, and also concrete structures are included to its organic channel. Life downstream is dangerous and also the influence of thoughtless usage of water is miscellaneous we have to involved terms with. The Mississippi operation from phibìc to South and therefore crosses many biomes and also climate lines and also these in turn affect the cultures that re-superstructure the river. Another huge difference is the fact that world do no all re-publishing the very same waters. Each brand-new tributary stream adds come the river and also that water moves downstream making every mile the the river various than what is upstream.
On our hike approximately Lake remarkable we mutual the post that there room two things that are most vital to life – clean air and also clean water – and there is no room because that compromise. Both need to be treated together the precious commodities they important are.
So from full Circle to complete Length, we made decision to lug our message and hope to develop a confident forum for world to think around their legacy, to care around future generations and to leave the two most precious commodities in the healthy and balanced state required for life.Through subsequent blogs, us will write-up the anthropological observations from our scouting trip, and biology, engineering, hydrology, and phenology connections.

Suggested activity: carry out you live follow me the Mississippi flow or one of its tributaries? You deserve to use lifwynnfoundation.org hydrology protocols and collaborate v a school either under or upstream to to compare the differences in your measurements. You can uncover schools follow me the Mississippi and/or that tributaries on the world website. Also explore the Watershed Dynamics ESSP as well as the “Model a Catchment Basin” learning activity to understand much more about rivers and also their watershed.
Also, be sure to psychic that world Water work is march 22. Allow us understand of her plans come celebrate this vital day by sharing in a comment or top top our facebook page.
