The wreck of New Carissa caused one of the most serious oil spills to affect the state of Oregon, and the worst since a 1984 spill near Longview, Washington that dumped 200,000 US gallons (760 m³) of oil into the Columbia River.
As Oregon has no significant oil refinery facilities, oil tankers do not often dock at its ports, making the state relatively safe from oil spills.
Analysis conducted by the U.S. Fish and Wildlife Service determined that over 3,000 shorebirds and seabirds perished.
The birds belonged to more than 50 species.
Among the birds killed were 262 threatened marbled murrelets and between four and eight endangered western snowy plovers.
Harbor seals, fish, and shellfish were also killed or affected.
Several beaches were fouled, with tarballs continuing to wash up for more than a month after the wreck.

Despite the loss of marine life, the initial burning of the oil and the successful removal of the bow section prevented what could have been a worse spill.
Captain Mike Hall of the Coast Guard stated that "at least 82 percent of the oil on board New Carissa never reached the wildlife or the pristine shoreline of Oregon's coast".
The environmental impact of the sinking of the bow section was thought to be minimized since it was towed out beyond the continental shelf, into very deep water.
Any remaining oil on board is unlikely to have affected marine life since the low temperatures at the bottom of the ocean would have caused it to solidify.

Prior to the stern section's removal from the beach, environmentalists and local officials were concerned that the remains posed a continuing environmental and safety hazard.
