The Upper Deschutes from Crane Prairie up to Little Lava is flowing strong and is a good pick for nymph fishing for whitefish and brook trout. Jigs and Perdigons and little Euro Streamers are awesome now.
Ants and Beetles are a great bet for dries, and look for caddis and pmd’s throughout the river and callibaetis in the Blue Pool area.
I have heard good reports on the Upper D from Wickiup down towards Sunriver. You’ll want to float it. Pound streamers off the banks and look for hatches of BWO, Trico’s (very early AM), PMD and Mahogany Duns. I doubt flows will be conducive for a good float for too much longer as Wickiup is dangerously close to going dry again this year, so the tap will be shut off soon.
