Carp will move into the shallow to spawn when temperatures reach the mid-60s to low-70s in the late spring and early summer. Carp prefer warmer water temperatures, so a cold front will push them back into deeper water until the next warm front comes through. During the spawn, you can see carp all over the shallows making quite a disturbance. Fishing for carp during the spawn is difficult because they move around a lot and are more into what they are doing instead of searching for food. The fishing is usually much better during the pre-spawn and post-spawn.
