These vessel traffic restrictions are necessary to facilitate fish sampling by the Illinois Department of Natural Resources in their efforts to prevent the passage of Asian carp into the Great Lakes.
These temporary restrictions to vessel traffic will allow the IDNR to safely gather essential data in support of the U.S. Army Corps of Engineers’ electric fish barrier that was constructed to deter the environmentally harmful fish.
To support these actions, the U.S. Coast Guard will enforce a safety zone on the Chicago Sanitary and Ship Canal. Vessel traffic will not be permitted to transit through the zone during periods of work. However, every effort will be made to allow vessels to transit when work is no longer taking place.
The restrictions will take place on the Chicago Sanitary and Ship Canal from the Lockport Lock and Dam to the fish barrier (mile marker 291-296.1) from 4 p.m. on Oct. 19 to 10 a.m. on Oct. 21, with the exception of a four-hour opening from noon to 4 p.m. on Oct. 20.
