Like many local bodies of water, both branches of the DuPage River seriously flooded after the "Flood of 1996," when approximately 17 inches (430 mm) of rain fell on the area within a 24 hour period on July 18-19 of 1996. Other flooding was very common along Washington Street, in Naperville, and Illinois Route 53 in Glen Ellyn, where those roads are close to their respective branches. The City of Naperville has torn down many of the affected homes and businesses in the former case, and DuPage County, with U. S. Department of Transportation funding, tore down many of the affected homes in the latter case.
The first written history to address the name, the 1882 History of DuPage County, Illinois, relates that:
| “ | The Du Page River had, from time immemorial, been a stream well known. It took its name from a French trader who settled on this stream below the fork previous to 1800. Hon. H. W. Blodgett, of Waukegan, informs the writer that J. B. Beaubien had often spoken to him of the old Frenchman, Du Page, whose station was on the bank of the river, down toward its mouth, and stated that the river took its name from him. The county name must have the same origin. Col Gurden S. Hubbard, who came into the country in 1818, informs the writer that the name DuPage, as applied to the river then, was universally known, but the trader for whom it was named lived there before his time. Mr. Beaubien says it is pronounced Du Pazhe (a having the sound of ah, and that the P should be a capital). This was in reply to Mr. Blodgett’s inquiry of him concerning the matter. | ” |
