What causes this

[DockShootinJack]

Normal wind patterns in your case is my guess. Trout do cause the same effect but it’s a bit different in appearance. Trout and feeding fish disturbing bait in salt water cause spots of slick water and not so much long outstretched calm areas. We call em slicks down here in salt water.

I had forgotten about those. Been away from the salt a long time

Interesting story and some good answers.

skeet has possibly the right answer as to what I have seen on occasion, one slick like that on a fine winter day on a grass flat was the ABSOLUTE best red ear ketchn I ever seen , my bud convinced me it looked fishy over there to him and first cast till the ice chest was full it was a red ear festival .....go figure

Yes, my father was a crappie guide on Toledo Bend till his passing and although we all grew up saltwater fishing they regularly caught school bass and crappie fishing slicks on Toledo Bend.

Wind has mass and flows very similarly to water, swirling around objects, rising over objects or terrain, forming eddies etc. We see it clearly as water flows, but can't see wind, only the effects. Watching wind on lake water is probably the best visual evidence of just how it flows. You can actually see wind currents, eddies, dead spots, even see a gust approaching on the surface of water. And of course, we've all seen that wind effect on water that looks like a dorsal fin moving along just under the surface!

My first thought was similar to that. I was thinking it was the creek flow with cooler water which would be denser and harder to move. I was also rooting for a "next time fish that weird looking thing". lol
