I have some experience fishing for carp as a kid. You will see lots in a group stacked up none of them will bite but if you see outliers around the group solo feeding tail up nose down often they will take a woolly bugger if you cast too them, that is my tip.Yes there are carp in Elk Lake - some very big ones, but they are not easy to catch. Need to research it and be patient as it can take time for them to bite.
