Corps of Engineers to start Grays Harbour dredging in April

Contracts & Tenders // March 16, 2017

The US Army Corps of Engineers will begin annual maintenance dredging at Grays Harbour in the Outer Harbour on 1 April 2017, utilizing the hopper dredge Yaquina.

Working around-the-clock through April 16, Yaquina will dredge the Grays Harbor Entrance, Point Chehalis and South Reach channels.

Yaquina will place dredged materials at the Washington State Department of Natural Resources-managed Point Chehalis open water disposal sites and the Half Moon Bay nearshore beneficial use site.

A second Corps hopper dredge, Essayons, is scheduled to arrive sometime in mid-April and work through early May to dredge the Grays Harbor Bar, Entrance and Point Chehalis reaches.

Essayons will place dredged materials at the South Beach nearshore beneficial use site and the Washington State Department of Natural Resources-managed Point Chehalis open water disposal sites.

The vessels are expected to dredge approximately 800,000 cubic yards of material from the Bar, Entrance, Point Chehalis and South reaches combined.
