otherwise naturally burn. Large fires in 1977, 1987, 1994, 2006, 2008, 2013, 2014, and 2017 have contributed to increased erosion, causing increases in sediment in the river and its tributaries. The excessive sediment degrades the habitat of aquatic organisms, particularly for coho salmon, Chinook salmon, sturgeon and steelhead.
