I hear so many different opinions on coho I don't even know where to start really. Methods seem to vary by region and run. Personally, I've had some epic (30+ fish) days and some epically disappointing days where I see countless fish but don't touch a one. I've had days where the guy next to me hooked none and I landed six in a few hours--both using the same fly, lines, sink tips. I even switched him spots a few times. Personally, I think chronically harassed fish in low water are going to be much harder to catch. When we get rain on the local rivers in the fall, I'm there hoping to run into a pod of fresh fish. I've caught them on purple egg-sucking leeches, sharp-steelies, Last Calls, egg patterns, MOAL leeches. My best days have been on smaller, sparser, bright flies like Idylwilde's Last Call. Unfortunately, I've rarely met two people who have the same opinions of coho. It's hard to get a consensus of what makes them bite.
