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.
I have changed the fly to 18 or 20 size RAB, I bought in South Africa last year. At my second cast I had a very aggressive take and a my first descent largescale on dry fly is in the net, I caught some smaller ones later on.
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.
