I cannot help but think that these lessons transpose to fishing in clear water, wherever that may be, and I am planning to employ some of these tactics more regularly when I fish back home in the states. If a fish sees the fly and doesn't eat it, switch patterns, right then. Drop the fly in clear water several feet from the fish you target, not several inches. Always drift the fly on the current side of the fish, and never between the fish and the bank in slack water. You only step and move when the fish is pointed or swimming away from you, and never cast or step when the fish is circling around, or pointed in your direction. It goes on and on, and I will detail more of this down the road.
