Keep in mind there can be up to 3 in a boat so actual number of boats would be hard to guess.
There will be a lot of boats and a bunch of knuckleheads running all over the lake.
I launch early go to an area and pretty much stay on the tm all day in that area, other than taking fish to weigh in. It's really not bad if you are observant of others at all times and realize that there will be a lot of amature boaters on the lake.
