Deep Tunnel has never reached its limit. After a weekend of heavy rains it’s almost full
Chicago's Deep Tunnel floodwater system is nearly full after heavy rains, with two reservoirs at 94% and 98% capacity. Eleven suburban communities face river flooding risks, and sewer overflows into the Chicago River are possible. Experts warn the system is insufficient and more water storage solutions are needed.
