Derelict dock washes ashore near Agate Beach north of Newport

Dock washed ashore near Agate Beach

On June 4, 2012, ocean shore visitors reported seeing a loose dock floating offshore near Agate Beach one mile north of Newport. The object has since washed ashore and is sitting at the high tide line.

Oregon Parks and Recreation Department staff responded to the site. The origin of the object is not known, but there is no obvious evidence it crossed the ocean. The dock itself is very large and heavy: 7' tall, 19' wide and 66' long. It is made primarily of concrete and metal, but is clearly designed to float. Because of its size and the chance it could continue to settle or be moved by wave action, state park staff are posting warning tape and signs instructing the public to stay off the structure.

A metal placard bearing Japanese writing was found attached to the dock  The placard (see photo), has been forwarded to the Japanese consulate in Portland, Oregon, for their review. The origin of the dock has not yet been confirmed.

The dock  is covered with marine organisms. Some are native, but others are specific to the waters of Japan. As a precaution against possible invasive species, the Oregon Department of Fish and Wildlife is coordinating a group of volunteers to remove the organisms from the dock starting Thursday morning, The salt water-dependent organisms will be removed from the beach. Among the exotic species are different kinds of mussels, barnacles and marine algaes. One invasive marine algae in particular -- Undaria pinnatifida, commonly called wakame -- is present on the structure.

Shortly after the dock made landfall, it was checked for radiation and was found to be negative.

OPRD is still developing disposal options. Two possibilities are salvage or demolition; both are being evaluated.

Agate Beach remains open ... just stay off the dock.
