Port Susan estuary takes a hit from warming, low Stillaguamish River flow

The early summer, with its unusually hot days and low snowpack, offers a window into the future for local scientists.
Researchers have turned their attention to Port Susan and the mouth of the Stillaguamish River. Important tidal ecosystems there have been dwindling over the past two decades, and a team is studying how tide marshes and estuaries can adapt to a warming climate. Other researches are investigating how changing river flows affect the way sediment is spread, and how that could harm fish and increase flood risks.
