I have a few local lakes, pretty small maybe a few acres each. It is a club that owns them but everybody and their brother fish them, so they have a lot of fishing pressure. The thing is I can go tear the dinks up like 10-12" on a weightless senko (I'm the only one around here that uses this I think lol) Now I know there are big fish in there because I see them all the time, I see a lot of 5-6 pounders (remember I'm in Indiana, thats pretty big). I cannot figure out how to get them to bite. This water is super clear, I mean clear, like I can see the bottom in 20' of water. The deepest spot in the lakes are usually around 30', and there are weeds (not sure what kind)and structure, and some cover. how would you try to get bigger ones here? It seems like when I do see the big ones they are usually cruisin a steep drop into deeper water, but HOW DO I CATCH THEM?

Fish the deeper water around the structure and weeds with weighted soft plastics during the day and crankbaits in low light. Specifically tubes, Kreature and Kut-Tail for your soft plastics. Lipless cranks, Norman Fat Boy, Bomber Square A and Bagley BII for hard baits. I would also fish jerkbaits, especially the Lucky Craft Staysee if you are fishing from a boat.

If you are comfortable with jigs, that would be another option.

I will try those. I also forgot to include that the only fish here are bluegill and bass with just a few crappie. So the food source will be bluegill and crayfish. Would that change anything?

Sounds like just plain over-pressured fishing.  Have you seen or heard of anything other than dinks coming out of there?

yea about once or twice a year someone will pull out a 6 or 7 pounder, I think someone caught a 6.5 on a nightcrawler a few weeks ago.
