We’ll be at the Duwamish Waterway Park on Saturday from noon to four for the Fifth Annual Duwamish River Festival. Food, fun, prizes, music, and yes, you can even make a birdhouse. You can also learn about the Lower Duwamish Waterway Superfund site and what’s being done for cleanup. Or you can just hang out with Bert the Salmon. Either way, stop by and say hello to several ECOSS staffers who will be on site.
