Robert, yes both the river (North Canadian) and the lake (Overholser) have carp. And I was also scouting the north cattail-lined shallows of Overholser. I do think I'll take my thermometer to where I was catching fish Saturday and compare water temps to where I was scouting for carp on Sunday. That's probably always a good thing to do this time of year as different bodies of water warm up differently.
