Can't get a bite

Hello everyone. I'm pretty new to crappie fishing and I have been on the water a few times this winter and can't get a bite. Anyone have any suggestions or tips to help me out. Or would let me in on what they use in the winter months to catch them and how they fish it. Also I have been fishing eagle creek reservoir for two years now and have yet to catch a real slab. I get a lot of smaller 9 inch ones. I'm guessing that reservoir just don't really produce a number of big ones so could anyone suggest. Good crappie lake as well. Thanks for all the help!

If I were you I would give Bigarm and Dave a call. They might help you out. They don't seem to miss.
