Abstract:

This document has been developed to evaluate the impacts of placing dredged material on a site located on Treats Island in Will County, Illinois, along the left descending bank of the Des Plaines river in the Dresden Pool. The proposed site is located between River Miles RM 279.6 to 279.7L on the island and lies between two parallel rows of old dredged material which was placed there during the 1930s. The area of placements is estimated to have a capacity of 14,000 to 15,000 cubic yards. This historic site is being studied as new because of the length of time between usage. Maintenance dredging is required to remove accreted sediments from the channel in order to provide a safe and unobstructed commercial navigation channel. Historically, dredging has been performed mechanically, with the dredged material placed at various locations along the bankline.
