8lb 4oz largemouth in August around 1999..caught her on a moss mouse no more than 3 feet off the bank. Best part of it...my buddy was fishing this area before me...duckweek all over the bank to about 10 feet out or so...there was a ring of tall weeds...well he was fishing all around it, I could see his moss mouse trails...I came over and on the first cast, I rolled it through the middle of that ring and the bass exploded on it.. I wish I had it on video. I'm assuming this gal if it was a female, would have weighed around the 10lb mark when spawning. I released her for another day...now the lake has turned over which was 8 years ago and most everything died out but has since been restocked. And no photos of her
The biggest largemouth I've ever caught was ~10lbs, 24" long in Cape Cod. Between MA and CT I've caught a total of four largemouth's over 20" and 7 to 10 lbs.
Of course I don't have pictures of any of them so hopefully I haven't imagined it all.
