Fishing - Having great luck lately...

I've posted here a few times but haven't in a while.
Anyways, I have a pond that a neighbor and I had stocked ourselves
with catches from another pond. The largest bass (largemouth) we had
ever put in there was probably 1.5 - 2 lbs. Nothing really big.
I've never had too much success in the pond over the past couple of
years since stocking it. Occasionally I would hook one but it seemed
like they were few and far between.
I went down to the pond this past saturday with my trusty Shimano
Curado and a sample pack of Berkley Gulp bait (someone had posted a
link to the free sample here about a year ago).
Anyways, I put on a plastic worm and threw 'er out and reeled 'er back
in several times. I decided to try a different tactic and let the worm
fall to the bottom (only a couple feet deep) and bring it in about a
foot, let it fall, repeat.
I got a strike fairly quickly and brought in a new personal best. 5lbs
on the dot and 19" long (measuring from the top lip to tail - from the
bottom lip to tail it was 20").
I didn't fish the rest of the day but went down to the pond today.
I snagged one - it got away. Got another bite, it jumped in the air
and shook my hook loose. Got another one - and reeled this one in. It
MIGHT have been the same one as saturday 'cuz he was 5lbs on the nose.
Back into the pond for another day.
So, I just went out there again and got another good
bite...unfortunately, this one shook my hook loose after it jumped a
foot out of the water.

So, question is - is it just that time of year?
The temperature is great here in North Georgia - high 70's - but it's
been a little overcast (it was actually raining today when I got that
last bite).
Is this prime fishing time or has my pond just finally started
producing good sport fish?
I've never fed the fish on a consistent basis but I also wonder if
maybe now that the frogs are gone, do they just have nothing to eat?

Any ideas appreciated.
