there are a few surprises along the way. Better teke it easy for a few trips til you locate them or start saving for a new lower unit. In fact as the water drops you will think"Man, I ran right over that snag a week ago!!"
Drop the trolling motor fairly soon and pay attention. I met a kid there one day and he told me he doesn't have a motor but has 5 or 6 tops close enough to get to with his trolling motor. He said he fished about every day and if they weren't biting there they weren't biting anywhere.
