Defunct 1950s

STOCKTON, Calif. (AP) — A containment boom has been placed around a defunct 1950s-era cruise ship that began sinking and leaking pollution in California’s Sacramento-San Joaquin River Delta, authorities said.

The 294-foot (90-meter) ship permanently moored in Little Potato Slough northwest of the city of Stockton began to sink in 13 feet (4 meters) of water on Wednesday, the U.S. Coast Guard said in a statement.

A sheen was observed on the water, and containment booms were deployed around the vessel and the city’s water intake pump station, the Coast Guard said. Photographs show the stern low in the water next to the slough’s grassy embankment.

It was not immediately clear what was leaking. The Coast Guard said the vessel recently changed ownership, so details about what pollutants were on board were unknown. The San Joaquin County Sheriff’s Office said the ship was leaking diesel fuel and oil.
