Dry fly fishing can be uncertain in early May. Nymphing is usually more consistent at this time of year. Fishing should improve as the weather gets warmer.

Cinygmula mayflies can be found during early May. They hatch at midday and are matched with a size 16 cream-bodied dry fly. You may catch the tail end of the blue-winged olive hatch through the first half of the month.

Some caddis will hatch in the late afternoon and early evening of warmer days. Match them with a tan/olive size 16 X Caddis .

The pale morning duns and green drakes get going during the second half of May, The PMDs will start first, and the green drakes follow one or two weeks later. Trout will focus on green drake nymphs for a couple of weeks before the hatch begins. A Poxyback Green Drake is an excellent imitation. Dead drift it near the bottom. Even after the green drakes begin to hatch, trout will prefer the nymph to the dun for several days until they become interested in the duns.

In the absence of surface activity, dead-drift a large golden stonefly nymph, such as a dark tan Kaufmanns Stonefly or Matts Fur (goldens are a huge part of the biomass on the Metolius). The fly needs to be near the bottom. Put another fly, such as a size 18 Pheasant Tail or a size 12 Poxyback Green Drakes , on a dropper or trailer.
