The vessel was reported to have four-hundred gallons of fuel onboard at the time of its sinking.
At approximately 10:30 a.m., personnel from Station Quillayute River reported evidence of a sheen.
The Quileute Marina Harbor Master surrounded the sunken vessel with a preventative boom on the surface of the water to contain any leaking fuel.
The owner/operator of the Miss Clarissa and Quileute Marina Harbor Master are making arrangements through a private contractor to salvage the vessel.
The cause of the vessel sinking is unknown at this time.
