If you all have the time, take a look at the picture I've attached. As some of you know, I'm a bank fisherman. From late February to Mid July is a killer at this lake. The lake is about 250'x1000'. The shallows up to about 10' out are covered with light lily pads, not the giant ones, but really small ones. Generally the depths run about 10' at the most, and most catches are 1-3lbs. I've caught some 4lbers and one 5lber, and I know that their has to be even bigger ones out there but I don't quite know what to use for this lake. A carolina rig caught me all those 4lbers, but now it's not working anymore. All my recent trips have been all failures to catch even the smallest fish. I've tossed a jig, crankbait, carolina rig, senko, etc. Tried all different techniques with each one and nothing. I know that normally during the early fall months the cool nights and cold fronts bring the fish shallower and shallower as the months pass, but what should I be using? Also topwater has been a huge failure. Just to add a little more information about this lake, the water is stained ( 1'-4' visibility with a white lure ). The bottom is covered with medium/heavy grass with some sandy spots so it sometimes makes it difficult to toss anything if it reaches the bottom, it is manageable but sometimes difficult to deal with. 

 

When it comes down to it, I just need help in lure or bait choice when it comes to this lake. Also how to find the fish period. Thanks for all the advice before hand!

hmmmm yeah sounds like they could be a flordia strain bass that just shut down in stupid weather but no topwater bite i would go somewhere else lol jk man. well i would experiment with colors and maybe try some swimbaits what is the bait fish in there and stick to as close to that as u can man sorry i cant help that much but fishing is tough everywhere in the summer

That pond looks to be pretty featureless and probably has very little cover other than the weeds you're talking about. Right now a lot of areas are either in late summer/fall transition periods, which usually equals tough fishing. The days are getting shorter and the temps are dropping and the bass are scattering. With all those weeds and silver dollar pads have you tried a frog through them? Hollow or something like a Rage Toad I would think would be good. Soft plastic jerks like a Fluke are usually good over the tops of weeds in shallow water or along the edges of emergent vegetation. If the submerged weeds have enough water over them I'd be throwing a rattle trap over them and ripping it through the weeds. If there isn't enough water for that I'd probably fish a bluegill colored chatterbait over the tops of the weeds. Either of those baits has lots of vibration and will call fish out of the weeds if they're buried up in them. Like KB08 said I wouldn't be shy about tossing a swimbait over those weeds either. 

I would start on the side of the lake where the wind is hitting and work from there.  The little fish will come in after the stuff that washes up, and the bigger fish will come in to feed on the smaller fish.

Literally there is no cover at all, other than the heavy submerged grass on the bottom

Another for a swimbait, and always recommend my #1 pond bait, a 10" or 12" Berkley Power Worm in black.
