The Columbia River Consolidated Materials Dredging Project consisted of dredging more than 1.2 million cubic yards of consolidated materials to -51 MLLW in the area between river miles 104 and 105 adjacent to the Port of Vancouver, WA.

J.E. McAmis utilized the backhoe dredge Megan-Renee and a custom built rock bucket to successfully dredge the difficult bottom conditions which included hundreds of boulders up to 8 feet across.  This project was completed ahead of schedule, with no lost time accidents and a perfect environmental record.  The U.S. Army Corps of Engineers Portland District issued J.E. McAmis an outstanding performance evaluation for the project.
