Flows have been dropping out of Island Park Reservoir making for tough fishing in Box Canyon. At Last Chance-Harriman, speckled duns and tricos are still providing some activity in the morning with terrestrials giving action during mid day. In the evening the caddis emergence provides some action. From Warm River to Ashton presenting big nymph patterns brings the best action, while below Ashton Dam action has slowed. Terrestrial patterns will be your best bet there for action.
We sure need some cool weather to bring back fishing action along “The Fork”. Spotty conditions have prevailed, but September is the month in which we begin seeing more activity from fish. Later this month look for BWOs to bring action along the lower river. Streamers are always a good bet for Box Canyon, the Tubs, and when float fishing anywhere on the lower river.
Look for action to pick up all along the river when we begin cooling in September. For now terrestrial patterns bring the best action during days when wind is not blowing a gale. The Warm River to Ashton reach is providing some action for those presenting streamers early and late in the day.
Look for better fishing after the wind dies. A hatching insect doesn’t have a chance to even mate in the winds we have had the last couple of days. Even the hoppers will hold on tight, but the wind is dying, so go back to placing terrestrials tight to banks and underneath overhead cover.
Hoppers and other terrestrial patterns tight against banks or evening rises to caddis swarms are the best way to find action up and down the river these days. We have some reports of good evening streamer fishing on the Warm River to Ashton section.
Terrestrial patterns are the way to go anywhere on the river. Even the Last Chance-Harriman reach is not crowded, but if you want to get away from crowds try Bear Gulch or Hatchery Ford. You will also find evening caddis swarms on all these locations. Don’t overlook pitching streamer into deeper water as the sun sets
It’s the “Dog Days” of August, so things are slowing down throughout the river. A few small PMDs and some speckled duns are on the water as well as caddis. Terrestrial patterns bring the best chance for action with mornings and evening being the best times on the river.
We are in the dog days, and action is slowing a bit. But terrestrials are saving the day. Fish ’em tight to the banks and as drift-free as possible. This applies up and down the river. We all think “hoppers” this time of year, but think also ants, beetles, crickets, etc.
