Success on the water starts with finding fish and not spooking them. No one ever caught a scared trout. All the tactics, the flies and the habits of river trout that we focus on mean nothing if the fish are on high alert and out of the mood to eat.
Don’t spook the fish. Achieving that is different from season to season. It’s different in various water types. And acceptable distances from the trout change even with the angles by which you approach them . . .
