The lake I normally fish always gets hammered with tournaments and there are always multiple people fishing. My problem is everytime i go to fish boat docks it seems there are no fish in the lake and i have tried everything from jigs to soft plastics to crank and jerkbaits. Does anyone have any other ideas plus the lake is getting really tough no matter what you throw at them im sure they see it two or three times a day. Any help would be great.

Find off shore structure and channel swings that don't get much pressure or make your own cover in deep water.  Lots of lakes have 2 different populations of bass.  The shallow dwellers see lots of baits while the guys who live deep don't see nearly as many.

What lake are you fishing? Boat or shore?

Go back at night. You'll think you're at a different lake.

I have success with spinners around and under docks.

try smaller plastics, maybe 4" or so.  You could also make sure you really slow down.  A lot of tournament guys seem to lack the patience required for really slowing down.  carolina rig might be a good choice also.

If at all possibly try and find areas that don't get fished as heavily. Also, try going deeper when it's hot out.

Try new things(baits/techniques) out if there is high fishing pressure there! Finesse tactics can be a good choice. Try fishing areas you haven't tried yet. Also, live bait is a great alternative man! It can tell you where they are than you can have more confidence in certain areas!

    Dropshot the pilings with a 4.5" Reaction Innovation Flirt worm.  The important thing to remember is DO NOT over work your bait.  You will be surprised how much action this thing has without you ever moving it.
