Many crops were damaged by flowing floodwaters or mud left on plants after the floodwaters receded.  An apartment complex was evacuated in Tudor Park due to flooding.

Heavy rainfall over the upper part of the Des Plaines watershed in Wisconsin combined with well above normal precipitation over portions of Lake County Illinois brought the parts of Des Plaines River into flood by August 20th. Additional rains on August 23rd resulted in crests during the following 3 days from points at Russell and Gurnee. Water inundated some homes along the river near Russell between the river and Kilbourne Road. Downstream at Gurnee, volunteers sandbagged around the Gurnee Grade School to prevent floodwaters from damaging the structure.  Flood waters inundated large areas of forest preserve along the river. Elsewhere in Gurnee flooding closed portions of Old Grand Avenue as well as Emerald Avenue and Kilbourne Road.  Sandbags were placed in front of several businesses along Old Grand Avenue. In North Libertyville Estates, a floodwall designed to hold flood waters from the Des Plaines River at bay, appeared to work as the area remained dry. In Libertyville, the Libertyville Golf Course at Riverside Park was flooded. The river crested at 10.55 feet at Russell on the 24th and at 9.82 feet on the evening of the 25th. High flows from near record flooding on the Fox River in Wisconsin were also moving downstream. These high flows, combined with excessive runoff over northern Illinois resulted in widespread flooding along the Fox River in the Chain of Lakes area. Homes in Antioch were surrounded by flood waters and many roads were closed. Most piers were under water and sandbagging efforts were ongoing.
