My scouting did not land me any big fish, but I determined there were bluegills, largemouth, pickerel, and what I think were grass carp though I was unable to catch them: big fish cruising just under the surface far out in the middle. The biggest thing I hooked was beaver, who got pretty upset about my having done that. I can't help casting to something that looked just like the big fish way out there!
I did also see plenty more enormous largemouth, most of which were following the smaller fish I was catching in. One was big enough to render me momentarily mentally disabled.
The beaver after I got it unhooked:
Oh, and I also found the biggest ant hill I have ever seen...
This will definitely be a spot to go to with big poppers either early in the morning or at night. I see behemoth bass in my future!
