The year’s first two substantial runs of salmon shot up the river the past two days, said Jay Peck from Jay Peck Guide Service. He’d see how the migration unfolds the rest of the week. The river, running at 335 cubic feet per second, became cooler, and was 63 degrees Tuesday morning. That’s probably why the fish, mostly Chinooks or kings, a few, not many, Cohos, came in. That day was warm, so the water warmed to the high 60s later in the day. That ended the migration for the day, and this was all normal. Jags of salmon will probably swim up in mornings in the cooler water for now, and the migration will probably build steadily. Jay’s trips caught salmon on black-and-olive wooly buggers in size 4 the first day and black-and-silver buggers in size 6 the second. The different colors and sizes probably had to do with the places fished. The flies were allowed to sink deep, and the salmon bit when the flies just began to swing. A little rain fell in the past week, and that helped the river’s level okay. If 3 or 4 inches of rain falls in remnants of the coming hurricane, that could be a game-changer, a positive one. Jay specializes in fly-fishing and catch-and-release, and books trips that fish with conventional tackle with his other guides.
