The Chicago River’s Natural Origins
The history of the Chicago River is a fascinating tale of both natural and man-made influences. While the river itself has been altered significantly over the years, it began as a natural waterway with important connections to the surrounding environment.
The Chicago Portage – a Crucial Passageway
One key aspect of the Chicago River’s natural origins is its connection to the Chicago Portage. The Chicago Portage was a critical passageway between the Great Lakes and the Mississippi River watershed.
This geographic feature allowed early settlers and explorers to transport goods and navigate between these two major water systems.
The Chicago River played a vital role in this transportation network, serving as a link between Lake Michigan and the Illinois River. Its location made it a strategic point for trade and travel, which eventually led to the development of the city of Chicago.
In the early days, the Chicago Portage was a narrow strip of land between the Chicago River and the Des Plaines River. This natural land bridge was crucial for Native American tribes and early European settlers to traverse the waterways and access new territories.
Early Native American Settlement Along the Banks
Long before European settlers arrived in the area, Native American tribes recognized the strategic importance of the Chicago River. The river provided a source of fresh water, fish, and transportation, making it an ideal location for settlement.
Native American tribes such as the Miami, Illinois, and Potawatomi utilized the resources of the Chicago River for thousands of years. They established villages along its banks, utilizing the river for travel, fishing, and trade.
These early settlements along the Chicago River were an integral part of the region’s history and played a role in shaping the future development of the area. Today, we can still see traces of these Native American influences in the city’s culture and heritage.

Reversing the Flow of the Chicago River
The reversal of the Chicago River is one of the most remarkable engineering achievements in the history of urban planning. This ambitious project was undertaken to address the issue of sewage contamination in Lake Michigan, which was the city’s main source of drinking water.
In the late 19th century, Chicago’s rapid industrialization and population growth had led to a significant increase in sewage discharge into the river.
Sending Sewage Away from Lake Michigan Drinking Water
Prior to the reversal, the Chicago River flowed into Lake Michigan, causing the sewage to contaminate the city’s drinking water supply. This posed a serious health hazard to the growing population. To overcome this challenge, the city devised a plan to divert the flow of the river away from Lake Michigan and towards the Mississippi River.
The first step in the process involved constructing a canal, known as the Chicago Sanitary and Ship Canal, which connected the Chicago River to the Des Plaines River. This new canal provided an alternative route for the sewage-laden water to be sent away from Lake Michigan.
By reversing the flow of the river, Chicago was able to protect its drinking water supply and improve the overall health and well-being of its residents. This innovative solution not only solved the immediate problem of sewage contamination but also paved the way for future urban planning and engineering projects.
The Incredible Engineering Feat
The reversal of the Chicago River was an engineering marvel of its time. The construction of the Chicago Sanitary and Ship Canal required extensive excavation and the use of advanced engineering techniques.
It involved digging a canal that spanned over 28 miles and required the removal of more than 40 million cubic yards of earth.
Additionally, the project required the installation of massive pumping stations to redirect the flow of the river. These pumping stations, such as the famous “Bridgeport Pumping Station,” were equipped with powerful steam engines that could move vast amounts of water.
The engineering team also had to overcome various challenges, including building locks and dams to control water levels and ensure the smooth flow of the river.
The successful completion of the project in 1900 was a testament to the ingenuity and determination of the engineers and workers involved. It not only solved the immediate problem of sewage contamination but also had a lasting impact on the development of the city.

The Chicago River as an Industrial Waterway
The Chicago River, which flows through the heart of the city, has played a crucial role in Chicago’s history as a major industrial waterway. Its development as a key transportation route and industrial hub can be traced back to the 19th century.
The Opening of the Illinois & Michigan Canal
The transformation of the Chicago River into an industrial waterway began with the opening of the Illinois & Michigan Canal in 1848. This canal connected the Great Lakes with the Mississippi River, providing a vital route for the transportation of goods.
The canal’s opening allowed for the easy movement of raw materials and finished products between the East Coast and the growing city of Chicago.
The Illinois & Michigan Canal not only made the Chicago River an important transportation route, but it also spurred economic growth and development in the region. The canal attracted businesses and industries, leading to the establishment of factories, warehouses, and other industrial facilities along the river’s banks.
Rampant Pollution from Factories and Stockyards
As industrialization boomed in Chicago, the Chicago River became a victim of rampant pollution. Factories and stockyards lining the river dumped their waste directly into the water, turning it into a cesspool of filth and pollution.
The river’s once-clear waters became contaminated with industrial chemicals, animal waste, and other pollutants.
The pollution of the Chicago River reached such alarming levels that it became a serious public health concern. The foul smell and contaminated water posed a threat to the city’s residents, leading to outbreaks of waterborne diseases.
In response to the growing pollution problem, various initiatives were implemented to clean up the river. The construction of the Chicago Sanitary and Ship Canal in the early 20th century helped divert the polluted water away from Lake Michigan, improving the water quality of the river.
Today, the Chicago River continues to serve as an important waterway for both recreational and commercial purposes. Efforts to improve water quality and restore the river’s ecosystem are ongoing, and the river has become a popular attraction for residents and tourists alike.
