The U.S. Army Corps of Engineers will begin the Grays Harbor maintenance dredging program next week with the USACE hopper dredgers Essayons and Yaquina.

The Essayons is expected to start dredging in the outer harbor of Grays Harbor around April 5-6, 2021 and will dredge approximately 23 days. 

The Yaquina will start dredging in the outer harbor April 8-10, working approximately 8 days, said USACE.  

Dredging operations will be performed continuously, 24 hours per day and 7 days per week, with all work concluded no later than April 30, 2021.

Dredging will occur in shoaled areas of the Bar, Entrance, Pt. Chehalis, and South reaches.  

According to USACE, the goal is to dredge approximately 800,000 cubic yards, with 600,000 CY placed in the South Beach Beneficial Use site (SBBUS).  

The remaining material will be placed in either the Half Moon Bay Beneficial Use Site (HMBUS) or the Pt. Chehalis Disposal Sites (PCDS).
