fall bass transition

any suggestions on the help in chisago area lakes for fall transition. last week fish still deep on rock and hard spots. spent monday on chisago and found one out of 5-6 rocks that had summer fish on them. did manage about 15-20 bass with some nice ones(3-5 range),but not like it is in the summer time. water temp 74-76. this time of the year they start to scatter but it amazes me how fast the fish move or shut down on the deep stuff.
