Yesterday, Lymm Dam: Damn, there's someone else fishing, only 99 out of 100 pegs to choose from

I'm feeling sorry for him already and it's only 5am. He's on the West side and going to be one very hot angler by the end of the day. I pick a place on the East side which I've fished before and will be in the shade until about 3pm. Very high bank behind me and an overhanging tree to my left, perfect.
I have a plan - Two rods, one 2:3 rod lengths out that I'm going to bait up and let the fish settle on it. If I start seeing feeding bubbles I'll top up and leave it for half an hour to let them get confident before I fish. The other for the margin which I'm usually a bit half hearted about but this time I'm going to give it a proper go. Groundbait's gone in on the long line and hemp and casters little and often with the odd few maggots in the margin about 2' from the reeds and 47" deep, 20s light wire hook and 3lb nylon hooklength. Started off with casters on the hook and getting bites and Roach straight away and all a good size, 5oz up with two or three over 8, guessed. It's a bite a chuck until it goes quiet. There's still no sign of feeding on the long line but I'll give it a try anway. Not quite as frantic but still picking nice Roach up on various baits, Tares, maggots, casters. Couldn't get much interest in sweetcorn. The long line has a bulk of 5 No8s at about 2/3 deep in 88". 16s Guru LWG on 3.3lb fluorocarbon. I wanted to try the tares hence a bigger hook than my usual 18s. It goes a bit quiet but I'm getting what I think are bites on the drop. Probably due to loose feeding. String the bulk out and yes, they've moved up in the water. Shallow up to about 2' and carry on catching with the Tares and all good sized fish. I wondered whether there were any tiddlers about so put a maggot on and sure enough, a tiddler straight away. Tares rule, OK
Fish of the day:
At some point in the afternoon the line goes behind the spool. It's a Daiwa TDM3012 and this is the first time it's ever happend. I'd done quite a few turns before I realized. Take the spool off and there's an almighty bunch of line trapped around and jamming the spindle. I'm trying to unpick it and drop the drag knob in the water

I can feel the bottom but can't find the knob. In hindsight I should have put the polaroids on, I might even have been able to see it before I stirred the bottom up. At least I've got the margin rod set up so finish off the day picking Roach up in the margin.
A wonderful days fishing. Love it
I'll just say something about the margin rod. It's a Grey's Toreon Tactical Float 10'6 although it's 11' with the butt extension. I don't use it very often, usually when I've got trees overhead. I'd forgotton how nice it is to use. It's light at 127g and IMO perfect for Roach. The progressive (Greys' description not mine) action soaks up all that jagging about that Roach do and swings smaller fish in no problem and I wouldn't have any qualms if something bigger did get a hold. I'm not greatly experienced with rods but it's hard to imagine a float rod better suited for light stillwater fishing at short range. The action probably isn't fast enough for rivers.
Just a little for interest. I took the temperature of the water top and bottom of the long line. Just with a fishing thermometer strapped to a marker float so it isn't lab standard but gives some idea of the difference. Top being about 4" below the surface:
5:30am Bottom: 19.5C Top: 20.5C
12:30pm Bottom: 20C Top: 23C
3:30pm Bottom: 20.5C Top: 25C
