Following a heavy rain event, a mixture of diesel fuel and lube waste oil was observed the morning of April 9, 2002, in the Rouge River. In the late evening of April 12, 2002, or the early morning of April 13th, another oil spill occurred after a heavy rainfall. It appeared the oil came from one of the combined sewer outfalls on the River Rouge (Baby Creek Outfall). This release was trapped in the River Rouge due to booming at the mouth, preventing further releases oil into the Detroit River. This spill was significantly greater than the first release. Oil released during the first spill impacted approximately 17 miles of shoreline in the United States and almost 10 miles on the Canadian side of the Detroit River, including approximately 1 mile of shoreline at the Lake Erie Metropark where oiled marsh vegetation was cut and removed. Over the course of the spill, oiled birds and reptiles were observed, including ruddy ducks, buffleheads, mergansers, scaup, coots, mallards, Canada geese, and one dead and two rehabilitated turtles. This Natural Resource Damage Assessment and Restoration Plan outlines the impact and proposed restoration projects to compensate for the impacts of the Rouge River Mystery Oil Spill.
