I, too, have noticed V-wake patterns in two deep section of a creek in a gulley in my backyard woods. It goes back and forth, swimming just below the water surface, so you see nothing on top of the water. When I first noticed it, I thought it was a duck swimming underwater, and I kept watching to see a head pop up, but it never did. I went down to the creek edge to try to see what it was, but it stopped moving when I was there, as if it sensed my presence or saw me. I thought it was probably two small fish (there were two separate V-wakes going back and forth) trapped in the deep section. The problem is that the swimmers are so fast that the V-wake pattern of the water as it swims by prevents me from seeing what it is. It also swam in a circle around a protruding rock. The next day, I saw one V-wake pattern going back and forth in the second deep pool of the creek. Since it went from the one deep section one day to the second deep section the second day, then I thought maybe it's just some sort of water bug, but Googling is failing me. Whatever it is, it zips back and forth really fast. On the second day, it again seemed to sense my presence when I got down to the creek's edge. I had to hide behind a tree for about 20 mins before it started zipping around again, but like I said the V-wake pattern it creates in the water obliterates being able to see what it is when it passes directly below me. The water was crystal clear and completely still, like glass. Watching it come head on towards me, all you see is the point of the V-wake. So it's definitely seems really small. From a distance, I thought I could see something, like maybe a small head, popping out of the water surface as it zipped, but that didn't happen when I was close to the water's edge. I wish I could find a video of what I saw or even an image, but no luck so far!
