Maybe we can have a technical casting/fishing strategy discussion. I was on quite a streak upon reaching this hole. I knew there would be a willing fish or two in here if I could get a spinner through there. I'm curious what others would do if you were fishing with spinners, or spoons, or plugs... There is absolutely no cast from below, the tree has grown into the water.
In my younger days, I would have cut my spinner off and tied on a small jig and undoubtedly pulled out whatever fish were in there. This would also be a routine spot to drop a fly into. Maybe I'm getting lazy, but now I just reconcile with the fact that the more time I waste here, the less time I'll have to fish more inviting spots upstream.
I ended up sending a spinner over the top of the stick that starts at the waterfall log and runs directly down the middle of the hole. I tucked it back in the corner as far as I could and got about 24" of retrieve which I did very slowly to increase my visibility to trout. This was enough distance to raise a brown from the depths and have it strike as my spinner was being lifted out. No hook up. Two more casts and no action.
The long parallel log above the waterfall made up for my frustrations though. Two trout succumbed to my spinner running down the length of the log.
I'd definitely fish it. I wouldn't try a bunch of different lures in the same spot. Usually trying more than one lure in the same spot doesn't produce for me, but there are exceptions. That generally works better on larger streams.
It's a lite tough to see in the pic but if there is an opening where a branch is about 8" off the water I might well be able to get something back in there but in reality there probably isn't so there no miracle casting happening. In a case that this, as much as I hate to admit it, I'm probably just moving past it. My thoughts are that you're not gaining much by fishing it. If you hook a big trout you're almost certainly losing it. It's probably going to take you a abnormal amount of time to get a decent cast in there and you'll probably miss the fish like you did cause the retrieve angle is poor. In the time it takes to fish the spot and mostly likely catch nothing I'd just skip it and catch two trout upstream in that same timeframe. So I'll take the defeatest attitude and just blow it off. Some battles are best left unfought.
How about clearing the spot out for next time??? When I started spinner fishing and I fished each stream 2-3x per year I would do things like that. Now that I only fish streams 1x per year, I rely on mother nature to do that work for me.
