If its a commercial water then there is a good chance there are matches on it, have a walk round at the weigh in at the end and have a look where the fish are being caught from and on what method- in winter it is often locating the fish that is the main problem.
Different waters obviously favour different tactics but if were fishing I would bring the following baits, some hemp, sweetcorn, 3mm feed pellets, softened with a few hookers and maybe some luncheon meat- this seems like a lot of bait but in reality you will only be using a handful of each of the baits in total.
If you are pole fishing I would look to feed maybe 3 swims, a deep swim 11-13m out directly in front of you and another at about 45 degrees and also a margin swim for later in the session.
The swim directly in front I would initially feed around 5-10 grains of hemp with 2-3 pieces of sweetcorn and see how the swim responds, if you are catching from the off I would feed every time you catch a fish, again with small amounts of corn and hemp. If your not catching feed very carefully probably every half hour at most.
In the 45 degree swim I would feed around 6 or 8 pellets and repeat the feeding process as described above. Dont be afraid to use paste either, you will still catch on it- just dont feed any.
Depending on which swim is the most responsive would determine what I would feed the margin swim with- dont fish under your feet like perhaps you would in summer- fish 10m plus down the nearside margin fish are easily spooked in winter.
If the commercial is of a decent size then i would definitely set up a feeder rod hair rig a small piece of meat on a straight led and cast all around your swim until you get a bite, remember to clip up each time so you know where youve been casting. I dont even bother feeding with this method- its more you finding the fish than the fish finding you.
I hope I havent told you how to 'suck eggs' but best of luck anyhow.
