History

Rock Falls was initially part of the Town of Sterling, created in 1838. In 1867, Augustus P. Smith purchased the rights to use the Rock River's hydroelectric power on the south bank, along with 65 acres of land on the river. Smith hired John Arey to survey the land, who soon platted the town in 1868. Rock Falls was incorporated into a village on January 26, 1869, and then incorporated into a city on April 16, 1889.

Due to low water levels in the Hennepin Canal, Illinois planners constructed a feeder canal with its mouth on the south bank of the Rock River. Initially, Dixon was proposed to be the location of the mouth, but surveyor Frank E. Andrews argued that the canal would be 11 miles shorter if the mouth were to be in Rock Falls, which was soon accepted. The canal officially opened on October 24, 1907, with an accompanying ceremony of almost 25,000 attendants, a 2 ½ mile long street parade, and a large aquatic parade to commemorate the opening, with Governor Charles S. Deneen in attendance.
