Help please! fishing S. Carolina lake

[redcarpet]

I live on a privite pond or lake, it's about 50 acers. I just hooked my 1st largemouth about 4 months ago. I've do alot of saltwater fishing, but I have to say that Bass fishing offers the most enjoyment to me.
I'M STUCK IN A RUT. The people that live on the lake say that ever year at the end of may the bass school and strick at bait fish, but the last to years have not been the great. I saw this and casted a tiny torpedo, and got 3 fish around 7:45pm. The next day I went early from 9:00am-1:30pm. I got three that day, but they were swimming along the sea wall, so when I saw them I would just cast to them and they would take it( jitterbug & torpedo). I didnt get any strikes without seeing the fish 1st. I did get a 5pounder my biggest so far.
The last couple of days Ive started at 4pm till 9pm. I can't get any action. Ive fished the banks with(JITTERBUG, TINY TORPEDO, ZARA SPOOK, AND A ZARA PUPPY wisth no strikes at all. Ive also tryed a RAD-L along the banks with no luck. I did get a 6in bass last night on my zara puppy.
I see them hitting the bait fish on top, and cast on top of them, but they will not bite.
I'll tell you alittle about the lake and what lures I use.Anyone that can help please do.
You can see about 9ft in the lake. The lake also has some saltwater in it from the ashly river. Lots of docks. No grass just sand. there are a couple bays if you can call them that, but that is where i get most of my fish. The water temp is about 86f
Thanks for you help!!!!!!!!!!
