Exxon Valdez Oil Spill

Shortly after midnight on March 24, 1989, the T/V Exxon Valdez ran hard aground on Bligh Reef in Prince William Sound, Alaska. In total, some 10.8 million gallons of North Slope crude oil spilled Oiled duck, click to enlarge Oiled Duck. EXXON Valdez Oil Spill Trustee Council. from the stricken vessel. An excellent summary of the spill can be found at the Exxon Valdez Oil Spill Trustee Council website. The Exxon Valdez oil spill remains the largest spill ever in U.S. waters, although it has since dropped from the top 50 largest spills worldwide. The Trustee Council states that this spill “is widely considered the number one spill worldwide in terms of damage to the environment, however. The timing of the spill, the remote and spectacular location, the thousands of miles of rugged and wild shoreline, and the abundance of wildlife in the region combined to make it an environmental disaster well beyond the scope of other spills.”

The Fish and Wildlife Service played a key role in response to this massive oil spill and trust resources managed by the Service were severely impacted. More than 35,000 bird carcasses and 1,000 sea otter carcasses were recovered following the spill. This is estimated to be a small fraction of the total number killed by the spill, since many carcasses sink, are consumed by predators, or float out to sea. The best estimate of total mortality is that 250,000 seabirds, 2,800 sea otters, 250 bald eagles, and billions of salmon eggs were killed by the oil spill.

The Service actively participates in the Exxon Valdez natural resource damage assessment and subsequent restoration activities associated with the civil settlement with Exxon. The EVOS restoration plan can be found on the Trustee Council website.
