This ^.
I fish a few really small ponds and puddles close to me that range from 3 to 75 acres. Most are 6-8 feet deep at most, some maybe 12-20 feet or so. I have caught fish over 6 lbs and some much bigger out of all of them. Around here if there are gills, shiners and crappie in there and the water is fairly green, they grow big. I think there are larger fish than most folks think in most places. Another plus is that a lot of these get weed chocked for a lot of the season, and that discourages people when it's warm, and early in the season, the pressure is light. Sure from April through June it can be a challenge with the pressure, but that's why God made Wednesdays...
