Episode Narrative Still supported by a nearby stationary front, a second round of thunderstorms dropped another 3-5 inches of rain across northwest Illinois during the overnight hours of July 23rd into the early morning of July 24th. This additional heavy rain exacerbated the ongoing flooding from the night before and caused even more extensive and severe damage. Yellow Creek and the Pecatonica River (Stephenson County), the Apple and Galena Rivers (Jo Daviess County), and the Plum River were most notably affected.
Event Narrative Heavy rains during the late night of July 23 and early morning of July 24 resulted in flash flooding of much of Jo Daviess County during the morning of July 24. Major flooding was observed along the Apple River near Elizabeth, where the river level was just below the bridge deck of Highway 20. Water rescues of stranded motorists were performed near Galena, Stockton, and Scales Mound between 4 am CDT and 630 am CDT. A bridge was washed out near Little Rush Creek and Bethel Road about 3 miles east southeast of Elizabeth, IL. A grocery store in Stockton was flooded with 3 inches of water.

Galena closed their flood gates around 5 am CDT on Saturday the 24th, and the Galena River crested about 3 feet high in front of the gates.
