Fishing on the South Fork has been changing day to day. The Upper section through Swan Valley seems to be a little temperamental from day to day. One day it will be on fire and the next nothing. I have found fishing through the Canyon early in the morning hours has been productive throwing streamers and twitching Chernobyl Ants. The warm clear sunny days have put the PMD hatches down and there are still a few Mahogany’s hatching. Cloudy and or rainy weather will get the fish up and eating mayflies. Fishing towards the evening hours is also effective. Zebra Midges are great droppers for a dry fly presented close to the bank.
The cottonwood trees are beginning to change color right now the next two weeks will yield some very picturesque views while floating the South Fork.
