On Tuesday, July 31, at 2:00 pm, the century-old dam along the North Branch of the Chicago River (3000 W. Argyle Ave) is being demolished to allow upstream fish migration and improve navigation and surroundings for boaters. This demolition is part of a series of restoration efforts by the United States Army Corps of Engineers (USACE), Metropolitan Water Reclamation District of Greater Chicago (MWRD), and Chicago Park District,
The North Branch Dam, which meets at the confluence of the North Branch of the Chicago River and North Shore Channel, between Foster Avenue to the north and Argyle Street to the south, will be transformed into a more accessible waterway for an increasing amount of fish, kayakers, and visitors to River Park. Funding will be provided by USACE, the MWRD and the Chicago Park District.
In support of the USACE’s River Riparian and Habitat Project, work in and along the waterways will be broken down into phases, starting with the restoration of approximately one acre of stream bed. The North Branch Dam and other concrete within the channel will be removed and riffles, step pools, cobbles, gravels, and sands will be installed. Anticipated future work will restore 29 acres of savannah habitat, 14 acres of riverbank and five acres of aquatic beds by removing invasive species and establishing native bank vegetation.
