Hoppers! I really do not need to say anything else on this report! The grassy fields of the Upper Owens River near Mammoth Lakes, Ca have been full of the leaping insects and the resident Trout have been taking full advantage of the situation, no doubt putting on some serious yearly mass for the seasons ahead. All sections of the river have been fishing well. Flows are clear and cool and very manageable. Normal bug activity is also noted in seams and foam lines. Nymphing various attractor nymphs as usual is very effective. Crowds have been here and there but usually one can find a place to call their own for the time they are there.
