A contractor working for the U.S. Coast Guard has finished removing the oil-soaked hull of a wooden minesweeper from Little Potato Slough, completing the last large vessel removal of the cleanup for the wreck-ridden waterway near Stockton, California.
The Sacramento-San Joaquin Delta has long been a catch basin for derelict vessels, some larger than others. For decades, the Suisun Bay area of the Sacramento River was home to dozens of decaying government ships maintained by MARAD, almost all of which have been towed off to the scrapyard to resolve an environmental lawsuit. But many more private vessels litter the narrow waterways upriver, and Little Potato Slough – a meandering waterway on the outskirts of Stockton – has become notorious for its wrecks.
The Coast Guard has been working on a large-scale cleanup operation to remove some of the most hazardous wrecks from Little Potato Slough, financed by the Oil Pollution Liability Trust Fund. Among other targets, it picked the HMCS Chaleur, a 140-foot wooden-hulled minesweeper that served in the Royal Canadian Navy from the 1950s up to the late 1990s.
Like many derelicts, Chaleur was resold multiple times after entering private ownership. It was moored at a private marina, which eventually closed its doors, allowing three vessels to deteriorate and sink at the dock. The Coast Guard has already removed two of the three, leaving Chaleur for last.
