Carps migrating characteristics, hum? I've got a few biggies in my pond. I also had some rainbow. I had a big flood as my ponds are both adjacent to a serious river that occasionally floods my BOWs. The trout all seemed to migrate, seems like 100% especially since it was in cold weather. The carp, however, stayed put. I see them when the Texas Hunter feeder goes off. Since they are generally bottom dwellers it's possible they are still in there. Hand throw some food and see what you see. I'd wait until the water warms to get a better feel since most fish are in a pseudo-hibernation mode in the cold, especially below 55 degrees. Much of this would never be certain.
