In winter there is very slight temperature difference throughout the lake.
There is little reason to fish the deepest part of the lake. I prefer to
locate the fish and then fish in their movement area. Throughout the year,
a depth of 5-10 feet is my preferred depth. Here (US), I prefer prepared
salmon eggs as bait in winter (treated to make them firm) , fished on tiny
trebles. This makes a nice cluster with a single egg on each hook. This
bait attracts numerous species, but may not be legal bait on designated
trout water. (laws vary greatly by location) Curiously, corn is also
illegal in some States and locales.

You may not be doing anything "wrong". Some species merely bite better in
winter than others.

My local lake (about 3 acres) has Carp, but no matter what I do, they
don't
feed in the winter! Boilies and nuts are banned BTW.

Surely sweetcorn over a spod of hemp should produce!

I plumbed, and picked the deepest water. Spodded one spod of Dynamite
Baits
hemp and sweetcorn, With a few trout pellets, then put a critically
balanced
3 sweetcorn hair as hook bait.

What am I doing wrong?
