You know your streams so you would know if there are better and deeper holes for the fish to winter in. I agree that the fish want to be deep, on the Clark Fork River in western Montana, I will nymph with 13 or more feet of leader below my strike indicator since the fish are in the deepest portions of the river, near structure.

I do see a little ledge in that hole so some fish may tuck in against that ledge but if there are deeper holes in the area with some good structure to hide under, that is where the bigger fish will be. They want soft water that carries plenty of food. The big fish have to eat at least 3 times a day during the winter. The little fish can get away with just one feeding, so you stand a better chance of catching a larger trout during the winter months.
