When fishing the Res there’s no doubt in my mind that the first thing I’m going to do is walk around the lake and spot signs of the carp. Confidence is key, so if you know you are where the fish are, you have a much better chance of catching them.
The Res is a weedy lake, and some people may get scared off by it, but there definitely are many clear spots. Personally, I would take as much time as I can to find a decent spot with a marker lead, so that you know your rig is presented well.
It’s obvious there is a very large amount of big fish in the Res, so the bait does get eaten! Using small PVA Bags or pellets generally works well, whilst being fished on top of good quality boilies in small amounts to start with. If you start to have bites, then for sure I’d put bait out regularly on the spot.
