A little carp wierdness

Had a pretty channel whack a pearl gold grub right at daylight and a bit later a six inch smallmouth. Then I heard a cry and looked up to see an eagle straight overhead as it winged its way upriver. About an hour later I found a nice eddy right below a small bar. I threw a three inch grub into the upper end and something hammered it and began peeling drag. It turned out to be a nice carp with the grub out of sight down it's throat. After landing it I walked twenty yards downstream and pitched the grub into the other end of the eddy. Whack, on the first cast another carp ate the grub! Now for the wierdness about a hundred yards downriver a pipe dumps warmwater into the river and the place was crawling with carp. You can see some in the last photo.Well these guys would shy away and spook from the same grub that the other carps chased down and ate. These guys actually seemed frightened as the lure neared them.
