Let the river run

My latest Science News feature explores what happens to river ecosystems when dams are demolished. In it I profile the mighty Elwha River, on the Olympic peninsula of Washington state, where two major dams were brought down over the past couple of years — a change that is radically reshaping the landscape. Salmon are now swimming upstream again for the first time in more than a century.

The story itself is paywalled for magazine subscribers only, but you can watch a related video for free (including some video shot by yours truly). For more on the Elwha, I highly recommend the documentary Return of the River.
