This much we know: Stormwater is nasty stuff. The state of Washington has called it one of the leading threats to the Puget Sound ecosystem. It can kill salmon within hours and it contributes to all kinds of health problems for species ranging from orcas to humans. What we don’t know, however, is exactly what’s […]

Finding a strategy to accelerate Chinook recovery
New in Salish Sea Currents: We continue our series on Puget Sound’s EPA-funded Implementation Strategies. This week we take on Chinook recovery. As threatened Chinook populations continue to lose ground, the state is looking to new strategies to reverse the trend. In the Skagit watershed, the scientists — and the fish — are among those […]
