Default Small plunge pool hydraulics

I was fishing a very small plunge pool yesterday, probably less than 4’x4’, when I found this guy – about 12” long.

After I released him, I shot this video of his underwater lair. What surprises me is that he’s holding by facing downstream.

The water on the surface is push hard away from the plunge, but just 12" below, it's the exact opposite. This is a steep gradient mountain stream, immediately dropping again right behind the camera, so I did not expect the water to swirl so strongly backwards.

I was using a hopper/dropper, so the surface flow on the hopper was dragging the Copper John downstream, even though the underwater hydraulics would've pushed a nymph back "upstream" towards towards the plunge (and the fish). I have no idea how he caught my CJ.

That's good fishing (always asking more questions). Thanks for sharing. How did you detect the take?

Very nice work on the plunge pool video, that was interesting to see that trout facing downstream!

I usually get strong strikes in small turbulent plunge pools close to the waterfall (unless I've missed a bunch of strikes and didn't know it!)
Perhaps the fish just don't have much time to decide to strike, unlike in slow, clear water where they will carefully examine the fly.

I often will cast into the waterfall to let it drag the dropper down deep into the pool. Sometimes I will get caught on underwater structure such as a branch, and then the branch shakes in the water flow very similar to a live fish trying to shake off the fly. Lots of false alarms!
Our local water levels are so low recently that I can take the chance to fish into structure. If I get stuck, I usually just reach into the pool and retrieve the fly.

Cool video. Clearly shows that things underneath the surface aren't always the same as the surface current. That's one of the things that makes subsurface nymph fishing challenging. It's a three dimensional game compared the two dimensional dry fly fishing.

Thanks for the response. Your experiences are very much like mine. I've had the opportunity to watch several "hits" on a lure without being able to detect a take, so I know I miss a lot of opportunities.

May I suggest everyone apply some reputation points to 'yikes' name for giving us a look at what lies beneath. I did

Very good of you to do that,

Ard

That is a really cool video; I've watched it ten times now.

I've dipped my fly in hundreds of plunge pools like that one and never thought that's how the hydraulics worked, or that's where the fish would set up. Now I'm cranking the gears in my head trying to figure out how this information can help me hook up next time I walk up on one of those pools. Thanks.

Peace.
