Some of the locks and dams on the Illinois River will get some work this summer. 

The projects start next month. U.S. Army Corps of Engineers Park Ranger Julie McDonald says the locks at Starved Rock and Marseilles will be shut down. Recesses will be put in to prepare them to be drained for more work next summer.

The Starved Rock and Marseilles locks and dams will be closed during the daytime for all of June, most of July, and half of August.

In the second half of August, they’ll be closed completely.
