I will usually go deeper and slow way down... One time I was fishing a tourney and we had three keepers in the livewell and the fish quit hitting. Sun had come over the hill. I told my partner the fish are deeper and I cast next to a stickup on the other side of the boat. This is the side away from the bank. That cast yield a 4.5 lb bass.. We then moved the boat deeper and started catching them again. We kept moving and fish deep to shallow. This means throw at the deeper structure first and then the shallower stuff next. We were using plastic nightcrawler...

You have to know what stage the bass are in, i.e. prespawn, postspawn, spawn, late winter, early winter, summer, early summer, early fall, fall, late fall....This comes from tow(time on water). Go smaller with your bait and slow down.... and maybe deeper for the bigger fish(depending on the time of year). Might try to pick one lake and figure out how the fish are moving throughout the seasons and this experience can be carried over to other lakes. After reading everything I typed, there is alot that goes into it and that is what makes it fun when you figure it out.
