This environment is defined by its complex hydrology, featuring numerous secondary channels and wetlands including Walker Slough, Hamilton Slough, and Paddock Slough. Named landforms like Indian Island and Millwoods Island sit within the river's course, while Thunderbolt Hill rises to the west of Portland.
