To maintain navigable depths, the
Swinomish Channel must be dredged at least every three years. Dedicated federal funding for continued dredging was eliminated in the 1990s. A study in 2004–2008 determined that sedimentation would render the channel's north end impassable for virtually all vessels by

2015, and its south end by 2019. The channel was dredged again in 2008. In 2012 the Army Corps of
Engineers received funding from Congress for another dredging project, which was finished in January 2013. The channel was most recently dredged in 2018.
