Documentation & facts about the Fordham Dam located in Rockford, IL.
Our dam was built in the mid 1800’s and originally used for Hydro Power. It is not a storage reservoir or a flood control structure. It’s considered a “Run-of-the-river” Dam. It currently artificially raises the water level in the downtown of Rockford between 3 -12 feet and as little affect further up stream. In addition, the timing of the gate opens has little to no impact on flood crests.
In 2019, a town hall meeting at Harlem High School with NOAA presented a very detailed explanation of river levels and Fordham Dam operations. This presentation can be viewed on the button link below.
