There here! Hoppers! Fish are keyed in on them and hungry. Throw a hopper dropper rig at the bank and hold on. While hoppers get a lot of play, don't overlook other terrestrials like beetles and ants, both of which can stay afloat with a size 10 Copper John hanging off it. Try dropping Hare's Ear, Princes, or Pheasant tail, any size to present a double threat to unsuspecting fish.
Big bugs are fun, but if your in the water in the morning or evening you may get a chance to fish a pmd or caddis hatch, although the window is short as the temperatures are well above normal this year. Also, streamers, including "the bling" and clouser patterns work incredibly well on the Teton.
The lower Teton River is accessible at the Newdale Bridge, the old Teton Dam site, Spring Hollow near Drummond or if your in a pontoon and wearing a life jacket - the slide at Bitch Creek confluence. Make sure your prepared if you decide to descend the Teton as there are many natural hazards besides the river including large backed up sections that can strand you on a windy day and rattle snakes. Stay on your toes and get out there and catch (and release) some of the sweet cutties on the Teton!
