Stay in the shallows. Far too many fishers will stomp into the water and prefer to be wet in the pockets of their vest or jacket before laying out the first cast. Experienced fishers can tell you how many fish have been taken in knee deep water. Even large fish move in the shallow parts, and many a trophy has been hooked before the fisher was wet on top of the boots.
A classical piece of advice is: fish before you wade! It still holds up. Why go in to the water at all if it's unnecessary to reach the fish? Stay on the bank or shore and leave the fish undisturbed. Undisturbed fish are so much easier to catch - not to say possible to catch.
Thigh deep wading is no necessity to catch fish.
Stay on the bank or shore or at least fish before you wade. René Palmér photo
