The other day, I was bank fishing a small lake.  The lake had some great structure, rocks, weeds, timber and brush.  The water was clear down to about 4 feet.  I was walking along the bank and noticed a flash just below the surface.  I looked down and saw a largemouth that had to be 7 plus pounds just sitting there in two feet of water about three feet from the edge of the bank.  I tossed my senko out past her and worked it slowly back toward her.  She ignored it.  I tried it again, but hooked a smaller bass in the same area. I then switched bait after bait trying to catch this lunker.  Spinners, jigs, swimbaits, topwater, jerkbaits, you name it.  I put it right in front of her face several times and all she would do was turn toward the bait and then slowly swim 5 to 10 feet away.  In a few minutes, she came back to the same spot.  She never really got spooked, she just moved around slowly, always coming back to the same spot literally 3 feet from the bank.  Meanwhile, I kept landing smaller bass all around her with the same baits that she ignored.  Once, I even bounced a rattle trap right off of her head.  Can anyone explain why this hawg would not take the bait while the others were more than willing to bite?

Sounds like she is spawning. These fish are catchable but it takes having a few different tactics, lots of time,and even more patience. Give her a couple days, keep at her. When she drops her eggs, she's gonna wanna fill that belly back up.

The smaller fish was probably the male.  One tactic is to catch and "hold" the male (livewell preffered).  This leaves the nest vulnerable (male is the main nest protector) and the female will take over on guard duty.  Now she is much more catchable.

Good luck, hope this helped

It may also have just been it was there warming in the sun, knew exactly where you were and what you were doing and had no interest in feeding. I was fishing a small lake in VA once where I made a number of cast long cast with top water, spinner bait and a fluke to a large, floating tree before deciding there was nothing around it and started easing by it. Boy was I wrong, there were about 10, 10+ pound bass side by side just holding under it catching the moring sun. They could have cared less if I was there. If I got too close they would slowly swim off until I moved away and then they would come back. I think when big bass move out of their feeding areas where the feel safe and secure, for what ever reason, just to check out the neighborhood, get a sun tan, etc. they have no interest in feeding and nothing short of a grenade is going to get one.

grenade. I gotta start thinking outside the box like that!
