Chicago Harbor Lock

With the decline in passenger transportation on U.S. waterways since the late 1800's, only a small percentage of Americans have ever experienced this mode of transportation. That makes a quick trip on a sightseeing boat one of the most memorable Chicago experiences for hundreds of thousands of tourists visiting the Windy City each year. Those who spring for a cruise which includes both lake and river travel will get a chance to experience an engineering novelty - the Chicago Harbor Lock. This is the device that keeps the Chicago River's water level below that of Lake Michigan, helping the river continue its unnatural flow. At the same time, it allows vessels to make the transition from the higher Lake Michigan water into the lower water of the Chicago River and vice versa.
