Here's a quick tutorial on reading water. Here is a piece of water on my local stream that continually gets overlooked by anglers. I am amazed how many guys I see walk past this type of holding water without making a cast into it. This type of water can be fished well with a float/jig combo or with spoons & spinners. Fish moving upstream out of the heavier water below will naturally hold here(right on the current seam) before moving up either the main channel or the side channel. It doesn't really matter how big the side channel is as long as there is sufficient depth to make the fish feel secure. Spots like this have been the most consistent producers for me on this river.
