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.
