Open-Hand, if you are going to come on the 18th-19th, be prepared to face a lot of other fishermen. There is a tournament that weekend and the lake is covered with folks - thicker than hair on a dog. You may want to get there on Friday to stake out a spot. Although that won't stop people from setting up righ on top of you.(Or stay though the holiday on Monday - you will have the lake to yourself).
I never have seen a depth chart of Bomo. Basically, things drop off pretty quick from shore. You can be in 30 feet of water, not 50 yards from shore. Depending on what kind of weed bed you are on, you can usually fish pike/bass and trout out of the same location.
I hear that the best spots are around Neshobe Island and the drop off around the fishing access.
