On a cold January morning in 2017, four-year-old Eli stands on the bank of Douglas River, hugging a dead salmon(鲑鱼) against his thick red coat. He looks up at his father, Andrew, who nods encouragingly. “Go ahead,” he says. “Put it in.” The young boy drags his feet forward and holds the fish as far as he can into the shallow water. “It’s floating!” Eli yells, delighted. For a moment, it’s almost as if the handsome salmon could come back to life.

Eli’s salmon is just one of 100 or so death bodies that will land in Douglas River in a half-hour activity this morning, deposited by dozens of volunteers. None of the salmon will rise from the dead, but Darrell Wick, president of the Douglas Society, who has promoted this gathering, is in the resurrection(复活) business.

Wick also leads the group’s campaign to recover this urban waterway’s salmon population. “The Douglas Society started looking into the possibility of recovering the salmon in the river in the mid-1990s, and part of a thought in that Lime focused on river recovery in cities worldwide. Back then, the prospects (前景) looked future lefts from the result.

Wick and his group are devoted to giving the river a full make-over. This monumental repair job, supported by approximately $95,000 of funding from the Pacific Salmon Foundation over the past 15 years, has involved recovering the river-habitat of salmon and preventing it from wearing away. Work on the river’s final section was completed in July 2017.
