The 98 acre lake I do most fishing in was great up until 2 weeks ago. I was catching nice bass every trip. Last 3 times nothing but pickerels. Some BIG ones too. The bass were up shallow around weeds along shore but now in those spots I only get pickerels. Did they eat the bass or did the bass move away from there?  

I bet those dudes will eat!

Its a time of year thing. Bass move offshore post spawn and will stay out there for a while especially when its hot. Sure there are some bass up shallow all year but not near the concentration there was pre and during spawn. I'm a bank angler and post spawn can be very tough.
