Spring vs. Summer carp location

I hear all these great things about late winter/early spring carp fishing, but i cant seem to find any. ive fished twin lakes, mamoth park lake and the alleg. river so far, been out 3 times and not one fish seen or caught in my normal summer spots. Where are they in general? ive been fishing on sunny warmish afternoons i thought for sure i would be able to find at least a couple, but i dont see any on shallow flats and no visible mud on the surface from feeding fish anywhere ive been. im using corn and worms btw, always do(at least til i get better w/ my fly rod). as always thanks any info is greatly appreciated.

They move all day long. There is no one set place to find them. Best thing to do before setting up is scout the lake and look for any activity.Chumming as you fish would hold them in place and get them active also but they will move on and hopefully another school moves in.
