The Chicago River, once "critical" to the development of Chicago, now transports a mere 3% of the region's goods and materials.

Rate this fact:

John Russick, director of the curatorial affairs at the Chicago History Museum, said:

But the water -- not just the lake, but the river too -- they were critical to our development. You don't get Chicago without them.

Yet a new report by the US Army Corps of Engineers found that the river may be costing us money, mostly due to environmental impacts of reversing the river's flow in 1900.
