We fished Sat and Sunday. I threw some jigs, and lures. Nothing was biting, but when I hooked a red wiggler under a bobber at about 2', the grandkids were pulling them out. My fish are about the same as yours. I've got some little green herons that work the pond. A kingfisher or two, and a GBH. I dont see the GBH as often as I used to. I've got pretty steep banks. I'm also a little north of you in NE Missouri. My water temps always surprise me. The top few inches of water are warm, but below that it's pretty cool. In fact, swimming on Sunday when the dog was swimming around me, he was stirring up the water. Darn near gave me hypothermia..
We ended up catching around 15 YP, 4 HBG, and a SMB, all on worms. Some of our fishing was in the heat of the day.

12 yr old pond, 1 ac, 15' deep.
RES, YP, GS, FHM (no longer), HBG (decreasing), SMB, and HSB (only two have been seen in 5 yrs)
I think that's about all I should put in my little pond.
