Sinclair Inlet is a shallow embayment in the western part of Puget Sound in Kitsap County, Washington, USA.
It was named by United States Navy explorer Charles Wilkes for George T. Sinclair, acting master of one of his ship's crews.
[3] The goal of the sediment clean-up was mainly to reduce the risk for humans of consuming bottom-dwelling fish with elevated levels of polychlorinated biphenyls (PCB) in their tissues.
Still, total mercury concentrations in unfiltered water from the Sinclair Inlet were roughly three times higher than those of central Puget Sound.
[4] In January 2017, the Suquamish Tribe, along with the Puget Soundkeeper and the Washington Environmental Council issued a notice of intent to sue the U.S. Navy for violations of the Clean Water Act, as a consequence of scraping the hull of an aircraft carrier, the USS Independence (CV-62), inside Sinclair Inlet, without an appropriate discharge permit from the United States Environmental Protection Agency.
In January 2020, the Navy reached a resolution with the tribe, agreeing to pump a layer of sand at least 10 centimeters thick into the area where the Independence was harbored.
