The snow is all gone up around the upper Klamath, the river has some color to it, but there are still plenty of fish and good angling to be had. Fish are keying on smaller BWO nymphs, some Rubberlegs, and some egg patterns. If you are swinging flies, think slow and deep. Try fishing intruders with sink tips, orange and purple are good colors besides the standard black and blue. Hartwick's Hosers are great patterns, and Bret's Klamath Intruders are tailor made for this river.
