How to catch bass and bluegill in the winter?

Well i can only guess that you are fishing Stevens Creek about two miles southwest of Cupertino, right? I have been here before and fished it as well. For bluegill your going to want to use a small piece of worm and try to get near structure such as trees that hang into the water were bugs might fall into the water bluegill will be gathered there. Next the bass, since this is a warm water lake, if were talking about the same one, bass will come in durning the evening to feed. You'll find them near rocky bottoms that meet weed edges. hope this helps.

In the deepest part and bluegill will normally bite night crawlers this time of year and don't use a bobber.For bass plastic worms or minnows would probably be best.

Winter, first of all, is a terrible time to fish. Bass become very elusive, and dont come to the surface very ofter, there actions become slower and do not want to chase after food. They tend to stay in the deeper areas at the center of the lake/river. So any chance of catching a fish, you'll have to put it right infront of there face. Good luck, and sorry the winter does suck.
