I was there a few weeks ago, and had my hook cleaned up of any night crawler 3-4 times before I could get any fish in about 15 minutes or so. Nibble, Nibble, gone. I could not figure out what was happening, so I shortened the bobber and put it very close to the bank where I can see the hook. Polarized glasses helped. Bunch of tiny bluegills, sniping from every side like piranha, just taking the worm away in pieces. So I changed tactics, instead of waiting for a pull down I started setting the hook when I saw a blue gill attacking and I had 12 or 15 in no time. Tiny ones, but it was fun.
