The Left Fork Fire burned heavily through the Kanab Creek drainage in early summer 2022. Summer rainstorms washed large amounts of ash into the stream, killing all fish in Kanab Creek. The upper East Fork Sevier River, from Kanab Creek downstream to Tropic Reservoir, appears to have also suffered large losses of fish due to the ash flow. The East Fork and all tributaries upstream of Kanab Creek were unaffected by the fire and still have abundant trout. Access to Kanab and Blubber creeks is closed due to ongoing safety issues from the fire.
