Hoppers! Do I really need to say anything else on this report!? The grassy fields of the Upper Owens River near Mammoth Lakes, California 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. Windy days? Yes! We love them! In this case many hoppers are blown into the water this making themselves available to feeding trout. All sections of the river have been fishing well. Flows are clear and cool and very manageable at around 65cfs. 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 on the edge of the unique Upper Owens River just down from Mammoth Lakes.
