There are many river users and functions to consider. The EIS Process will consider 14 different alternatives, some of which call for the removal of the Sixth Street Dam. Design engineers and resource agency staff will be determining the best method to restore the historic rapids near the Sixth Street Dam while allowing the most benefit for all river users and the environment.
All of the dams in the Lower Reach will be functionally removed from the river and more natural hydraulic elements like riffles, runs and pools will replace the existing riverwide hydraulics created by the dams.
