    Protecting The Great Lakes

    Protecting the Great Lakes is vital to millions of people from Illinois and throughout the Midwest who rely on these waterways for their livelihoods. Asian carp eradication measures include increased fish collection, population suppression, biological control efforts and electric barriers. These methods assist in the prevention of Asian carp bypass between the Des Plaines River and the Chicago Sanitary and Ship Canal (CSSC) as well as the Illinois and Michigan Canal and CSSC during flooding.

    Lake Michigan Water Allocation

    The Inner Harbor Breakwater, built in 1874 and sealed in 1938, has been leaking water from Lake Michigan into the Chicago River. The Chicago Inner Harbor Basin Cuttoff Wall project was constructed in 2001 to help alleviate the problem of withdrawing water from one watershed and discharging it to another.

    William G. Stratton Dam at McHenry

    The Stratton Lock was constructed in 1960 at Stratton Dam, on the Fox Chain of Lakes at McHenry. During the summer months, over 24,000 boats pass through the lock to and from the Fox River downstream but the Lock does not have the capacity to meet the current peak demand. The Dam's sluice gates, constructed in 1939, have reached the end of their useful life and new gates will allow better regulation of water flow to minimize flooding.
