J.E. McAmis Project Update: Bonneville Dredging Begins

J.E. McAmis is in the process of dredging upstream of Powerhouse II at the Bonneville Dam for the U.S. Army Corps of Engineers, Portland District.

The dredging involves work in more than 80′ of water and is focused on removal of sediment and debris upstream of the powerhouse turbines.

Upon completion of the upstream work, McAmis will shift operations to the Bonneville Project’s Bradford Island Fishway, where additional accumulated sediment will be removed and disposed of at an upland facility.

According to the company’s announcement, the dredging work started on February 7th and must be completed by February 28th.
