Silverdale’s waterfront is seeing the effects of recent storms in our area, as documented by Susan Digby, a geography instructor at Olympic College.
High stormwater flows have washed litter, debris and dead salmon into Sinclair and Dyes inlets, where currents and winds from the south carry the materials to Silverdale’s beaches, including Silverdale Waterfront Park and Old Mill Park.
“The north end of Dyes Inlet is like the end of a sock,” Susan told me. “When we get rain and wind, everything piles up there.”
Photos of all this debris — including parts of three docks — were taken by Susan on Sunday, just two weeks after her students cleaned up the beach entirely as part of an ongoing study that counts and categorizes marine debris that collects there.
A phenomenal amount of trash winds up on our beaches, including discarded food wrappers that people have carelessly discarded. Just about anything that floats can wash into a stream or storm drain to be carried into one of our local inlets. Some debris may be coming from the nearby streets and parking lots in Silverdale, but some could be coming all the way from Gorst, as suggested by drogue studies (PDF 1.6 mb) conducted by the Navy.
As Susan points out, the debris includes lots of Styrofoam, which can be ingested by birds and sea creatures, as well as baby diapers and syringes, which are a reminder that disease organisms are making their way into our local waters with uncertain effects on the fish and shellfish we eat.
I plan to cover Susan Digby’s student research project in more detail early next year, after 2012 data are compiled.
