==Course== The Pilchuck River originates in the Cascade Range. It flows generally west until it reaches Granite Falls, then it turns and flows south, passing by Lochsloy and Machias before emptying into the Snohomish River near Snohomish.

==Human history==
Suburban development along the river's course in the mid-to-late 20th century resulted in declining salmon runs and the placement of obstructions that damaged fish habitats. Mitigation work began in 2002 under the Washington State Department of Transportation (WSDOT); the Pilchuck River had begun to threaten sections of State Route 92 near Granite Falls with erosion.<ref name="Herald-2024">{{cite news |last=Zamora |first=Connor |date=July 9, 2024 |title=Project aims to restore fish habitat to the Pilchuck River |url=https://www.heraldnet.com/news/project-aims-to-restore-fish-habitat-to-the-pilchuck-river/ |work=The Everett Herald |accessdate=November 13, 2024}}</ref><ref>{{cite news |last=Bray |first=Kari |date=December 30, 2014 |title=Pilchuck River gnawing at stretch of Highway 92 |url=https://www.heraldnet.com/news/pilchuck-river-gnawing-at-stretch-of-highway-92/ |work=The Everett Herald |accessdate=November 13, 2024}}</ref> A house was swept away by the river in 2012 and continued to threaten other properties, resulting in a 2016 WSDOT project to stabilize the banks and reroute the river.<ref name="Herald-2024"/><ref>{{cite news |last=Bray |first=Kari |date=March 3, 2016 |title=Pilchuck River is steadily eating away at properties in Lake Stevens |url=https://www.heraldnet.com/news/pilchuck-river-is-steadily-eating-away-at-properties-in-lake-stevens/ |work=The Everett Herald |accessdate=November 13, 2024}}</ref> Additional work to create new fish habitats in the river by placing logs tied to large rocks began in 2024.<ref name="Herald-2024"/>
The Pilchuck River Dam was constructed in 1912 southeast of Granite Falls to provide drinking water for parts of Snohomish. A second dam on the site was constructed in 1932 and included a fish ladder.<ref name="Times-Dam">{{cite news |last=Mapes |first=Lynda V. |date=August 5, 2020 |title=Another Washington dam removal – I and 37 more miles of salmon habitat restored |url=https://www.seattletimes.com/seattle-news/environment/another-washington-dam-removal-and-37-more-miles-of-salmon-habitat-restored/ |work=The Seattle Times |accessdate=November 13, 2024}}</ref> The dams prevented salmon from accessing the upper Pilchuck watershed; by 2019, the annual salmon run had declined by 99.6 percent of its historic counts.<ref name="Herald-Dam">{{cite news |last=Sanders |first=Julia-Grace |date=July 6, 2020 |title=A major fish barrier on the Pilchuck River is coming down |url=https://www.heraldnet.com/news/a-major-fish-barrier-on-the-pilchuck-river-is-coming-down/ |work=The Everett Herald |accessdate=November 13, 2024}}</ref> The Tulalip Tribes and city government of Snohomish planned for the dam's removal in the 2010s and received funding from government sources and a grant from the Paul G.
