Salmonflies are the kings of their species, the largest of the stoneflies. Every May these magnificent bugs emerge from the Deschutes, Rogue and Klamath rivers to breed a new generation of bugs, and fly anglers are there to take advantage of the resulting feast for trout and steelhead. This week we talk to ODFW fishing ambassadors Chris Clogston and Luis Alvarado about their passion for the salmonfly hatch, tying big "ugly bugs" as they call them and why May is one of their favorite times of the year to find the big trout on some of Oregon's most iconic rivers.
