"PILCHUCK RIVER, Snohomish County — With a thunderous roar, the Chinook
helicopter emerged above the treetops. Four uprooted trees, root wads and all,
dangled from its belly.
Attached by cables, the trees soared over the river before being released to
their resting place in the water. They will remain here for decades, but their
impact may be felt for much longer.
This was a helicopter-assisted rescue mission for the Pilchuck.
Pacific Northwest rivers evolved with big wood. Trees would tumble into the
river, slowing it down, pushing it into its floodplain and creating a complex
tangle of side channels, shaded pools and the small cobbles and gravels needed
for salmon to spawn.
But for over a hundred years rivers like the Pilchuck were clear-cut of their
surrounding forests, dammed and channelized, and wood was systematically
removed from rivers to improve navigation and simplify flow patterns, making
them more susceptible to harmful summer heat and surging winter storms.
Guiding these rivers back to something that more closely resembles what they
used to be is one way to give the Northwest’s salmon a better shot amid
drought, warming temperatures and winter storms stoked by climate change."
