The biggest I have caught there is 3lb. I have caught a ton in the 1-2lb range. I too have heard many stories of big bass caught there. They have to be there, they have plenty to eat!
Sounds like my experience at Little Pond too. I've been going there most of my life. I used to see a lot of crayfish when I snorkeled there as a kid ('70's & early '80's). Haven't seen any the last few years with my nephews.
Still an awesome little body of water to paddle around in.
My last time that I went to little pond is last year at April. I caught salmon on my last trip and I stopped going there. Since I was focus into other species. Definitely holdover fish. 4pounds and 7 pounds. Will look at my phone if I have picture of it. Of course, they was released back.
Fished from shore yesterday from 12-3, No bites but something massive followed my swimbait towards shore. I could see it 5 feet in front of me as I was wading in 3 feet of water and it hit the lure twice but no hookup! 
Then it took off and I couldn't coax it out of the depths again.

It was chasing my 5" Sebile Magic Swimmer sinking Blue gill swimbait. The problem is that its weedless and the hook is fairly large and inside the collapsible body (Similar to the Hudi). If it was a treble or smaller It woulda hooked up no prob. Cuz of the wind/waves I couldn't see what type of fish- thinking a Trout or maybe the elusive landlock Salmon we all hear stories about in this pond. Totally gave me new hope for the pond after seeing it though. There are definitely large fish in there.
Yeah, I've had some big fish follow the bait to me and not take it! Anyway, got 1 rainbow, a couple of strikes and a couple of follows from trout. Couple of other people there and 1 bass boat showed up. 
Hard to believe that today is Feb. 1st! Doubt if there have been many days this mild on April 1st!
