Mechanical clamshell dredging of Grays Harbor, Inner Harbor, Washington, will begin on July 16, 2025, and is set to continue 24/7 until February 14, 2026, with a pause from September 28 to December 1 for the Tribal fishing window. The project, led by the U.S. Army Corps of Engineers (USACE), Seattle District, will target shoaled areas in Aberdeen Reach, Cow Point and Turning Basin, Hoquiam Reach, North Channel, and Crossover Channel. Dredged material will be placed at the South Jetty and Point Chehalis Placement Sites. The federal channel will remain open, but all waterway users are urged to maintain at least 300 feet from dredging and disposal areas to prevent damage to boats and gear. This maintenance is essential for safe navigation and supports the economic vitality of Washington’s waterways.
