Beautiful place with lots of fish and no private boat houses because it is entirely surrounded by a national forest. There are a handful of major marinas with large boat houses. A sonar unit with GPS is necessary because it has numerous small islands that can make it easy to lose track of where you came from if you're not familiar with the lake. The north side of mid-lake, north east, and east ends have hydrilla and other stands of vegetation down to about 20-25 feet that hold fish year-round. Visibility can reach 10 feet or more in most of the lake regularly, but you can also run up the several tributaries to the north, east and west to find muddy water if you're more comfortable in muddy water. If the current trend continues, it is likely to be flooded at that time (it was last year). Most of the fish will probably be up shallow in flooded brush, especially around bluegill beds, like James mentioned. Bags in the upper teens are good but it is not uncommon for it to take 20-25 lbs to win a single-day event there at that time of year.
There really are good fish in all parts of the lake. So, if you're going there for a tournament, I would suggest that you burn lots of gas first and find an area that you feel comfortable with, something that matches your strengths, and learn what they're doing in that area. I have caught good ones and good numbers in the north end, mid-lake, in Crystal Springs down south, in the east, and way up the river in the west so I don't think it's a lake where being in the "best area" is absolutely necessary to be successful.
