When dams come down, what about the ocean?
In late August, Steve Rubin, a fish biologist with the United States Geological Survey, will dive into the frigid, briny water of the Strait of Juan de Fuca, roughly a mile from the mouth of the Elwha River. It will be Rubin’s 12th dive at the site since the Elwha Dam was breached in 2011, sending a century’s worth of accumulated sediment surging downstream.
The megatons of sediment that were released by the dam’s removal were expected to help rebuild the twists and turns of the Elwha River. But some feared that they might end up suffocating the coastal ecosystems near the delta.

To make a longer story short: There were big changes at first as sediment covered up the seafloor and blocked out sunlight, but in the long run the system rebalanced itself and it's all good. Two environmentally destructive and potentially dangerous dams are gone.
