Brownstone,
I'm a little surprised, I would have expected Newfoundland to have similar regulations as Cape Breton Island's:
Pool Rotation
Pool rotation can be summed up very simply: -Take your turn, and cast and move. -Should you arrive at a pool, and other anglers are there ahead of you, it will be expected that you wait your turn before entering the pool. A waiting area is usually obvious where waiting anglers gather until it is their turn.
-When it becomes your turn, you will start at the upstream end of the group of anglers, and follow the group through the pool.
-While moving through the pool, it is the usual practice to take 2 casts and then take a step downstream. Be careful not to move too far out into the pool near the fish. This may cause the fish to move away or cause them to be less likely to take a fly.
