We've got a ghost story for you. The Klamath River, running through the rugged Northern California mountains, used to hold the fourth largest population of salmon and steelhead in the world. Every year millions of fish would surge up stream. Now, over fishing, agriculture, and bad politics have taken their toll, and the once great runs are not only diminished, they are mostly gone. To many fly fisherman, the Klamath might as well be dead. But angler Ryan Peterson has heard rumors that during the winter, a run of massive steelhead creep upstream unnoticed. Is it a good yarn or is it real? This season Ryan wants to find out. The search for the ghost run begins.
