Public commenter: Army Corps seeks local agreements to continue Fox River dam study; Geneva to monitor

During public comment at the Oct. 21 meeting a resident reported that the U.S. Army Corps of Engineers has asked municipal governments along the Fox River for a "nonbinding" letter or agreement by Jan. 30, 2026 allowing the Corps to continue studying the impacts of possible dam removal. The commenter said the Corps's request is intended to support additional environmental and cultural-resource study and is not an immediate order to remove dams.

The commenter said the Corps indicated removal work would not begin before 2028 under its planning timeline and cautioned that federal and state processes are lengthy. He urged municipal officials to sign the nonbinding step to allow study to continue so elected officials would have the analysis needed to make future decisions. The committee noted the Illinois Department of Natural Resources, the Army Corps and local municipalities are engaged in varying roles and that the city has posted a Fox River dam update page summarizing the process and the IDNR outreach.

Preservation Partners representatives in the meeting summarized their interest in mitigation for cultural resources if removal goes forward; the commenter flagged a locally significant feature (the Potawatomi Golf Course island/peninsula) as an example of a place that may need mitigation or study.

Commission members and staff said the nonbinding letter under discussion is intended to permit further study and that any actual removal would require later environmental review and consultation under federal procedures. Staff noted a city web page with the IDNR letter and related materials was available for the public.

Provenance: Public comment on dam studies appears in the meeting transcript beginning at the 7106-minute mark for public comment; staff and partners responded later in the public-comment segment.
