The Fall River is good, as expected with some spring in the air near Sunriver. Still quite a bit of snow on the ground there, and keep in mind some vehicles should not attempt to drive to the Tubes as that road is rough and floods easily with melting snow and rain there are huge, deep puddles to get through.
BWO, Midges, Little Black Stones are the main hatches.
Fall River get a surprising hatch of March Browns this time of year, and it should pop any day now.
Chugging a foam Hippie Stomper is a good method for exciting hatchery trout to eat at the top.
Eggs and Jig’s and Mop’s are picking up nice fish on a Tightline Nymph rig.
Small Streamers are always a good bet at the Fall and can provide some of the coolest chases from trout, and in that clear water it can make your heart race for sure.
