Finally I got to a deep spot by the huge rock where good size fish was rising quite frequently.
First cast on a Elkhair Caddis brought me a smalscale as the fly touched the surface and no more action on that fly.

At around 9:00 I decided it's time for coffee and breakfast, so back to the camp.
I have still a lot to learn about all around presentation of dries, there were loads of fish, but I've struggled to make them try my flies.
