i have just joined a local club medlock angling society the water ime fishing is an old park lake that has been updated and now looks terriffic it has been relined and has a constant depth of 3to4 feet no big carp here as it is used asa match lake by the club matches are won with weights of 20ib pluss i fish the pole and have had some decent fish at 11 13 mtrs i fish a no six elastic through top 2 sections with 31b main line to 21b hook length joined by loop to loop i set 2 rigs up the other sme lastic but through top section only both rigs have milo 4 x 12 i shot one with styles and a 20s kamasan ready tied for my light rig 18s with an olivette and droppers for rig i put ground bait on both lines fish white maggot on hook feed a few by catty i soon get bites and catch small chub roach then some decent tench to 11b pluss skimmers seem to catch one then no more then a couple of perch then it goes dead as u can see place is like an aquarium stuffed with fish any ideas on how to keep them there once  i start catching r my rigs right 

i would miss the groundbait out pot in a few maggots and then pot in just a few maggots each fish start on the bottom then come shallower as the fish move up to the falling maggots.or feed one line on the bottom pot in some damp lightly squeezed small pellets so that they get to the bottom fish a slightly larger pellet on the hook. 

Well done Nige, I couldn't get past the first 3 lines!!!

Geoffrey  if youve put groundbait in at the start and fish maggott over the top and are catching then just remember to keep topping up with small balls of groundbait with a bit of feed in.  Mix your groundbait on the dry side as the venue is quite shallow and keep the balls small but regular.  The key to keeping the fish in your swim is to feed them.

talk to the match anglers on the venue.

Agree with Slime. These types of heavily stocked, match fished lakes can tend to be waters where the fish become accustomed to what the majority of anglers are doing. There are often one or two methods that outscore everything else.
