When fishing the murky waters of the Red River in Manitoba, I have found that a jig fishing like retrieve works for carp. A gentle lift and pause followed right away by another lift and pause will allow you to better detect the very gentle take of the carp. Let the nymph drop back to the riverbed and repeat. Sometimes I jig-jig-pause, sometimes jig-jig-jig-pause. Important point is to not jig too much (maybe a quick 4 - 6 inch line strip), and to apply the second jig within a second or two so you have a chance of hooking the carp. Be ready to set the hook if you feel resistance in one of your jigs.

While this tactic will not guarantee you will hook every carp that inhales your fly, it will help. The benefit is that the carp will sense your nymph moving and by the second lift may have inhaled the fly and you may set the hook.

I have also found dapping to work for carp fishing near the shores of a much cluttered shoreline.

Works for me, hope it works for you.

EDIT: btw, my go to fly for carp in murky water is a Bead Head Prince Nymph
