Okay here is another question. I was out today on the Truckee River in CA. In one area the river dropped a fair amount and the water was quite fast. There was lots of structure. I wondered if in the water behind a break like a large rock is there gravity pulling the trout down stream or with the break is the only pull if any strait down. I wondered because I was trying to decide if it was worth fishing the areas behind the rocks in the fast water or move to a bit calmer run. (This was very fast)
