Fishing Gravel Lakes

[J@k3 01s3n]

I had never fished a gravel lake, but there is one that looks pretty nice that I stopped at the other day. I know there were bass there because they were jumpin' that day. I threw a bomber model A for a while, nothing... a bomber long A jerkbait, nothing.... pumkin berkley tube 3", berkley power worm 5", yum dinger 3" and 5", buzzbait, spinnerbait... all nothing! I have had bad days, but 4 hours and no bite is a real bad day, especially when i see the bass jumpin'. My question I guess is, what do you think I was doing wrong? I don't know much about fishing gravel lakes, so maybe someone might have some ideas or tactics they find successful in gravel lakes. I know its also possible that I just happened to get skunked that day. Well, thanks in advance for the help!
