Arboretum Creek

Gazing at Arboretum Creek, can you sense the echoes of the Duwamish tribe? They called this area “Staʔáb,” meaning “Fathom.” A village thrived east of the creek’s mouth, and Foster Island, now serene, was once their sacred burial ground. Arboretum Creek, a seemingly tranquil waterway, holds a vibrant history, deeply entwined with the land and its people. This area, part of what was once a narrow isthmus connecting the Montlake area to the University grounds, was a vital portage route for canoes traveling between Lake Union and Lake Washington. The creek itself has seen drastic changes. In the 19th century, extensive logging disrupted the watershed, increasing silt and necessitating human intervention for storm management. A trestle, later filled and converted to Madison Avenue, further diverted its flow. Imagine the dramatic shift in 1917, when the opening of the Montlake Cut lowered Lake Washington by almost ten feet, exposing mudflats around Arboretum Creek’s mouth. These flats became a dumping ground for city refuse, a stark contrast to the vibrant ecosystem envisioned today. The creek suffered further indignities. Neighborhood development in the 1920s diverted its water into underground pipes, part of a combined sewer overflow system. Even today, this system sometimes releases untreated water into the Montlake Cut during storms. The creation of Lake Washington Boulevard added insult to injury, channeling road runoff directly into the creek, and the final stretch was piped underground below the Wilcox Bridge, creating a barrier for fish. Arboretum Creek, once a thriving waterway, was reduced to a series of stagnant pools in warmer months. Now, hope blossoms for Arboretum Creek’s revitalization. The Friends of Arboretum Creek are working to reconnect the creek with its historical water sources, Alder and Alley Creeks. This project promises to bring over 40,000 gallons of fresh water daily, year-round, restoring life to the creek and reducing pollution in the Montlake Cut. The project’s scope has expanded to include flood protection for the Japanese Garden and nearby streets. As you stand here, envision Arboretum Creek teeming with life once more, a testament to the enduring connection between humanity and nature.
