With some shrimp, you'll catch hard heads, gaftop, reds and trout.
There are some specific areas to look at in the lake. I would recommend getting a Kayak and fishing Mud Lake (north of Nasa rd 1). Don't eat anything from the creek if you go up that far.
Around the park, during the winter, look for the deepest hole you can find.
