When reading or watching videos on about reading water for fishing in English, I often come across terms like riffle, run, pool, seam, among others. However, when I get o the river ready to float that dry dropper over the riffle, I'm not so sure if I'm targeting the right area. I'm not even sure I perfectly understand what these terms mean.
Can someone help me to make sense of these terms and of which cues should I look for when reading the water.
I often read that seams are where two currents meet each other, but what should I look for? Pictures from the internet don't always look like what I see at the river. I can see that there are different currents when I have my line across more than one, but is that the only way to find seams? What are the general visual cues?
Pool and run (also beat) are somewhat confusing for me. They seem to refer to the same thing: a stretch of fishable river water. Yet, how do I know where the pool/run/beat starts or ends? I know that this should be at the head/tail of the pool, but what should I look for to find these?
I learn that riffles are faster shallow parts of the river, and I usually look for white foamy water. What is the difference between that and a rapid? Is it just a matter of semantics?
