Firstly - Hi Steve and welcome to the forums
I'm with Geoff on this one - maggots and sweetcorn. Both will provide you with bites even more so the maggots and bites can mean fish.
I'd be inclined to go for the smaller ones initially because there's no better way of regaining the thrill of fishing than catching the first fish.
You did'nt say what tackle you have but a float rod, fixed spool reel and some line around the 5lb breaking strain should see you through.
Try 'laying on' with a float initially over a bed of loose feed. Laying on is a method of fishing where you have the float to hook set slightly overdepth, typically 6inches. Within five inches of your hook put a number six shot, the rest bunch around your float, with the exception of 2 (in 5ft of water) size 6's spread equal spaced down your line.
Hooksize, either a 16 or 14 which will allow you to use a bunch of maggots or a single grain of corn without having to keep changing hooks.
Get yourself a plummet if you haven't already and check your depths before fishing, again a 1/4oz one will be ample. Look for flat areas on the bottom preferably where the sun will have been shining on over the last few days.
Once you've located some throw a good couple of handfulls of maggots and a small one of corn into the area, cast over it and wait.
Don't be inclined to throw more in initially but wait until you've had a bite or a touch that will indicate that the fish are there.
Once that happens, feed a little bait at each cast. If the bites stop, stop the feed, if the bites keep on then feed. I know it's a bit open ended but without being there it is hard to say exactly how much and when but it's a good guide.
By now you should have a fish, hopefully
If not, try another part of your swim, same tactics but this time don't forget about you previous baited area. Every now and again, cast back into it and see if there is a response, also inbetween, about once an 1/2 hour throw a small amount of bait into it.
Finally, we expect to see your report on Friday pm or Saturday, good luck, Dave
