I have been to LOTO and while the waves were not 8 foot there were areas were I would say we dropped down 6' and that was outside party cove and there were no "big" boats there at the time just a butt load of smaller ones. I was blown away that a lake could get like that. I can also see it getting like Chart said if you had a few of the larger boats running down the lake in some of the narrower areas.
+1. 8' waves on LOTO? No. 8' holes? Yes. I'm 5' 11" and standing in my boat I have been at the bottom of one of the infamous "holes" created by all the boat wake cross-chop and have looked directly at the top of the "wave" next to me. The corner leaving party cove directly across from PB2 can be some of the worst water on the lake.
