The Department of Ecology is investigating after an oil spill on Hood Canal

The Navy says they were transferring oily bilge water onto a dock when an alarm went off, meaning that transfer did not shut off when it was supposed to. That spilled the oily bilge water onto the dock and into the water.

The Navy said the spill was about 150 gallons They boomed off the area, put skimmers out and used oil absorbent pads.

By Tuesday morning there was a slick as long as a mile-and-a-half that came all the way up to the Hood Canal Bridge.

The Department of Ecology is estimating the amount spilled is 2,000 gallons. The effects of the spill on wildlife and property are not yet known.

Both ecology and the Coast Guard are expected to be back on the scene Wednesday.
