The diversion of water from the Lake Michigan watershed is of major importance to the Great Lakes states and to the Canadian province of Ontario. The states and province that border the Great Lakes have concerns with the long term effects of diversion. To insure that the concerns of these interested parties are considered, the U. S. Army Corps of Engineers has been given the responsibility for the accounting of flow that is diverted from the Lake Michigan watershed.
The Chicago District operates and maintains eight navigation projects on the Illinois and Indiana shores of Lake Michigan. Our mission encompasses lock operations and maintenance, breakwater repair, maintenance dredging, and the collection of hydrographic survey data
