I have just stocked my 3 acre pond in December also. I stocked 3" bass. 1-2" bluegill, coppernose and redears. I have also stocked way more fatheads than you guys. I'm not sure the exact total now, doesn't really matter because you can't over do fatheads, but it has to be about 40 - 45 pounds. I have built minnow beds with tires, chicken wire, pvc pipe, and quick crete. If they don't have the cover to protect them the bass will scarf them you faster them you can put them in. I also threw out a couple hundred pounds of cotton seed meal to feed the fish.
I'm like you guys in that I see absolutely no fish activity and even the kingfishers are gone. I hope like you guys that they are just deep and inactive. Maybe a senior pondmaster will enlighten our fears.
