Shell Creek is a natural, spring-fed creek that originates near the eastern boundary of Yost Park, a large city-owned park in Edmonds, Washington that has been preserved in a largely natural state.
The attached report was prepared for the City of Edmonds to establish baseline information on stream conditions in order to support work toward meeting National Pollutant Discharge Elimination System (NPDES) permit and ESA requirements. This report covers all of the appropriate significant streams under the City’s jurisdiction.

Who knew that baby salmon were such explorers?
The long-held understanding that baby salmon emerge from the streams where they hatched to head out to sea actually is missing a far more complex story — and a far more interesting one, scientists explain in a new paper.
On Saturday, April 12th, Megan Moran from Sound Salmon Solutions and Joe Scordino released several thousand Coho fry with the help of volunteers and local residents. These “baby” salmon were released in Yost Park near Olympic Avenue and near Holy Rosary parish in Edmonds. It was great fun.

EDMONDS — The city of Edmonds has work to do on Perrinville Creek.
On Friday, City Hearing Examiner Phil Olbrechts decided city staff must address safety issues about a corroded pipe that connects the last few hundred feet of stream to Puget Sound, and consequently restore fish passage along the lower portion of the creek.
For decades, toxic tire dust has choked coho salmon before they can spawn in their natal streams. Now, King County scientists say they have made a “potential breakthrough” in how to save them.

A bipartisan group of Washington legislators has filed a bill in Olympia asking Congress and the Trump Administration to modify the Marine Mammal Protection Act to allow lethal removals of sea lions and harbor seals and other actions in more of the state to save ESA-listed Chinook and other salmon populations.

In early 2000, scientists at 3M, the chemicals giant, made a startling discovery: High levels of PFAS, the virtually indestructible “forever chemicals” used in nonstick pans, stain-resistant carpets and many other products were turning up in the nation’s sewage.
For decades, Coho salmon were turning up dead in urban streams the Pacific Northwest. The salmon would stop swimming straight, and then die before they had a chance to spawn. Researchers worried that unless they figured out the cause, the species would eventually go extinct.
