You need to get a map of the lakes new structures and brush piles.I don't care to fish the crowds,most just sit in 1 spot and wait for the fish.I look for brush in or near deep water and also like to fish the rock humps.You can pick up a nice laminated map with a lot of the gps cord and shows a lot of the brush piles too.You can pick one up at Five Season Bait and Tackle in Cedar Rapids for around $4.00.
