7:02 PM: A reader texted us that photo late today, saying the state Department of Ecology was investigating a reported fuel spill into Longfellow Creek at the West Seattle Golf Course. “Dead fish and odor in the creek on the 12th hole,” the text said. We contacted an Ecology spokesperson, who had not heard about it; since then, Seattle Public Utilities has tweeted, “Vandalism of an approximately 250-300-gallon gasoline storage tank has caused a fuel spill at City of Seattle’s West Seattle Golf Course. Gasoline has reached Longfellow Creek. SPU’s Spill Response team is on site and coordinating with (Ecology).” More as we get it.

7:51 PM: Just talked with the Ecology spokesperson we originally spoke with earlier, Ty Keltner, as well as with SPU spokesperson Sabrina Register. Keltner said Seattle Parks first discovered the spill early this morning, then contacted SPU, and notified Ecology this afternoon. A cleanup contractor already has been hired, they said, and they confirmed that dead fish were found and so the Department of Fish and Wildlife is involved in the investigation. Register said the cleanup and SPU personnel have booms out and will be on scene overnight; she’s not sure exactly how much got into the creek and how much of the fuel was stolen, but she says Parks recovered about 70 gallons.

9:13 PM: Our original tipster says they first reported this to Parks after noticing it while walking the golf course this morning. They shared a photo of what they described as the area where the tank is, by the golf course’s maintenance shed:

“The gas was flowing from there and then into the catch basin by the 18th tee box,” they said.

12:25 PM SATURDAY: We’re working on a detailed followup (coming up separately later this afternoon) after talking with SPU at the spill site and seeing cleanup crews at the creek. Not much additional information yet but cleanup work continues.
