I'm wondering if there's a "better" topographic map of Truman Lake than the one I currently use -- it's the "Fishing Hot Spots" map you can buy at Wal-Mart, etc. and shows contour in 10 ft intervals as well as fairly vague types of structure. It gives a good general idea of what the bottom looks like, but I'd bet there's something better. I'm looking for something with more detail, including specific underwater structure like brush piles, old bridge pilings, etc. Anyone know if there's a better map available and where I can get it if so?
