The Chicago River is 156 miles (251 km) long, and flows through downtown Chicago. == Geography == The northernmost branches of the river are the West Fork, the East Fork (a.k.a. Skokie River) and the Middle Fork, which join into the North Branch at Morton Grove, Illinois. The North Branch meets up with the Main Branch of the Chicago River at Kinzie Street in Chicago. The Main Branch flows due West from Lake Michigan, past the Wrigley Building and the Merchandise Mart. == History == In the 1770s, Jean Baptiste Point du Sable built his farm on the northern bank of the river, the first non-Native American settlement of Chicago, and early in the next century, Fort Dearborn was built on the southern bank of the river. In 1900 the river's flow was reversed in order to keep Lake Michigan clean. In 1915, the ''Eastland,'' an excursion boat docked at the Clark Street bridge, rolled over, killing 812 passengers. In 1928, the South Branch of the Chicago River between Polk and 18th Street was straightened and moved 1/4 miles (400 m) west to make room for a railroad terminal. === Reversing the flow === Originally, the river flowed into Lake Michigan, which allowed sewage and other pollution into the clean-water source for Chicago. This contributed to several public health issues including a major cholera epidemic. In 1871 much of the flow was diverted into the Illinois and Michigan Canal. In 1900, the Sanitary District of Chicago completely reversed the flow of the river using a series of canal locks and caused the river to flow into the newly completed Chicago Sanitary and Ship Canal. Before this time the Chicago River was known by many local residents of Chicago as "the stinking river" because of the massive amounts of sewage and pollution which poured into the river from Chicago's booming industrial economy. Up through the 1980s, the river was quite dirty and often filled with Waste; however, during the 1990s, it underwent extensive cleaning as part of an effort at beautification by Chicago Mayor Richard M. Daley. === Chicago Flood === In 1992 the Chicago Flood occurred when a pile driven into the river punctured a hole in the wall of the long abandoned Chicago Freight Subway near Kinzie Street. Most of the 60 mile (97 km) network of underground freight railway, which encompasses much of downtown, was eventually flooded along with the lower levels of buildings it once serviced and attached underground shops and pedestrian ways.

This article says that the river was reversed in 1900 into the ship and sanitary canal by the chicago sanitary district. The Illinois and Michigan Canal article says it was reversed in 1871 into that canal by the army corps of engineers. Which is it? User:Rmhermen 22:08, Oct 8, 2003 (UTC) The river was ''partly'' reversed in 1871 into the I&M Canal, yet usually still flowed naturally, with the reversal occuring after heavy rain. In 1900 the River was ''permanently'' reversed into the Sanitary and Ship Canal, with it always flowing backwards, as it does to this day.
