Looks like you have quite a herd there! Well done! What else is in the pics besides CC?
There are some OTS CNBG in amongst them, but it looks like they are getting pushed around at feeding time. Those CC are chow hounds. The CC may have been coming to feed all this time and I just wasn't able to see. I'm feeding about 6 to 7 cups a day spread out over the day at morning, noon and late afternoon. I bet the CC is what's been gobbling up those June bugs I've been chunking in there.
Oh yeah, there are some RES in there, but I don't know if they are coming up to feed. All my research says probably not.
I'll tell you what I find amazing. One day you go out to the pond and it looks completely taken over with FA. The next day you get some breezy conditions or a rain and presto your pond looks crystal clear.
Oh yes, one more thing. New depth taken from several places in the middle and it ranges from 6'2" to 6' 11"
