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. [3] Rock Falls was incorporated into a village on January 26, 1869, and then incorporated into a city on April 16, 1889. [4]

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. [5]

In 1927, debate began on merging the City of Rock Falls with the neighboring City of Sterling. Supporters of the merge cited the severe lack of public services such as a library and hospital, while opponents argued that the merge would result in higher taxes for the residents of Rock Falls. On November 22, 1927, Rock Falls voted in a referendum on whether or not to merge with the City of Sterling, with the referendum failing with 69.7% of residents voting against. [4]

Due to industrial decline throughout the Rust Belt of the United States beginning in the 1970s, Manufacturing industries in the city began declining, along with the population. Heavily reliant on Sterling's industry, Rock Falls suffered in the 2000s following the closure of Northwestern Steel and Wire in 2001, RB&W in 2003, Lawrence Brothers Manufacturing in 2006, and National MFG Co. in 2010. Due to the Great Recession, more businesses in the region closed, with the poverty rate of Rock Falls reaching 19.6% which continued to increase. [6]
