The Metropolitan Water Reclamation District of Greater Chicago (MWRD) works around the clock to provide flood protection for Cook County. We monitor the weather, and prior to major storms, we draw down the waterways to provide maximum capacity for stormwater. Our goal is to provide maximum capacity in the area waterways, tunnels and reservoir system to provide as much protection from flooding as possible.
On April 18, we reversed the Chicago area waterways to Lake Michigan to alleviate overbank flooding and provide additional capacity for stormwater. The gates were opened and closed as follows:
Wilmette Pumping Station gates were opened at 1:25 a.m. on April 18 and closed at 6:45 a.m. on April 19
Chicago River Controlling Works gates were opened at 3:47 a.m. on April 18 and closed at 2:06 a.m. on April 19
O’Brien Controlling Works gates were opened at 6:15 a.m. on April 18 and closed at 5:15 AM on April 19
We encourage the public to minimize the use of water in their homes before and during rain events to reduce the amount of water flowing into the sewer system. This will provide maximum capacity for combined stormwater flows.
