The contractor, Tacoma-based American Construction Co., has removed nearly 220,000 cubic yards of material from the channel, according to John Pell, project manager for the U.S. Army Corps of Engineers. The work is expected to finish on Jan. 12 or 13, bringing the project to completion within the so-called “fish window,” which closes Feb. 15.
A dredging machine was working at shoaling areas just north of La Conner on Tuesday, and from there will work its way south past downtown La Conner, finishing at the spot known as “Hole in the Wall” on the weekend.
After the dredging is finished, the Corps will conduct a post-dredge survey and publish full charts of the channel afterward, Pell said.
The 11-mile channel silts in quickly and requires dredging to keep it passable. It was last dredged in 2008 and was due for additional dredging in 2011. In late August, the Corps, which oversees the dredging, awarded a $1.9-million contract to American Construction Co. for the work.
