well tbh i have no idea how my bait is presentated, i am fishing in about 3ft of silt with a bottom bait with a lead clip set up so for all i know the bait could be buried deep into the silt.
i would guess the fish are feeding in the silt a lot because in the evenings carp are jumping out more than usual
But the rod have been casting towards the deeper part of the lake has only produced one fish for me so far (other rod is in the margin so i have a very light lead, don't have to cast far and using a multi rig, so i doubt my hook and bait has dug into the silt) so i could of got lucky and could be missing a lot of chances, if i found my hook was deep in the silt i would even though they could be feeding deep in the silt i would change my set up so the bait is on top because i think i would be a lot more likely for the carp too find and get hooked on my rig.
