Believe it or not, the fish often set up looking downstream into the return current of the eddies, at least when feeding on top. If I fish the dammed areas with a nymph or streamer, I usually throw the fly into the spillover, let it get dragged down (you may need a few splitshots) and then fish the drift back through the deep part of the pool. If fishing dries to rising fish, I let the fish tell me where they want it, but more often than not, that means throwing into the tail out and dragging it into the backward eddy current, then mending to get a somewhat drag-free backward drift. The fish in these pools get hammered. Regardless of the dozens you will see holed up there, spend some time fishing elsewhere and you may be better rewarded.
