On 12/27/07, West Strait of Juan de Fuca from Dungeness Spit west to Cape Flattery closed and reopened on 2/11/08. In Jefferson Co.: Oak Bay which closed in 2006 recorded 563 micrograms of PSP toxin in butter clams on 1/28/07. This was the most toxic PSP sample for this region for 2007, even though this was old toxin from the previous bloom and did not indicate a new bloom. Previously, blue mussels set a new record at this site for PSP toxin at 4,821 micrograms on 8/21/2006. Commercial PSP closures: There were Geoduck Tract closures in the strait of Juan de Fuca at Protection Island, Siebert Creek, and Freshwater Bay. | |
