Sloth, The Hoh and the Duc fish like night and day for springers because of the usually differing levels of water clarity for each. The Duc will be crystal one day and on that same day the Hoh will be puked because of the spring melt-off. For the Duc I'd fish with a diver and sandshrimp. Metallic blue is a good color this time of year for this river. Fish the Hoh with more traditional king gear. This includes Vibraxes, bouncing gear and K-15's with bait wraps. Oh yeah, don't forget the Hoh is closed (and the Duc is S-L-O-W).
