NF Clack generally has less water than the Fish Creek gauge indicates but is a much smaller creek. Can be run lower if low elevation rain event. Can be scouted
Recognizing and having a plan for the portage around this waterfall can be the crux of the run. Portage on the old road/trail about 50m above the first 10-15' waterfall or run the first waterfall and portage the main waterfall on the left. Bring rope and watch the exposure if you choose the second route.
