Commenting on the 'lake is full and closed' item, not the booking discussion.
A number of years ago when I previously lived in the DFW area (where I once again now live), it rained over 24" in a 3 week period. All the lakes here in N. Texas were closed. Many, many people were very upset and couldn't understand why.
Here's the best description and reason posted then, and probably applies now.
When there is that much 'rise' in the water, the new underwater hazards are not known or recognized at all. Case in point:
All of the picnic tables/areas that were at one time 'lakeside' are now underwater and in the lake. That, and in many cases the lake is so full that it has created 'washout conditions' on a lot of properties.
Just think about running around the lake on plane, and having either your boat or lower unit, find one of the many 'concrete picnic tables' that one finds at the lake acting now as an underwater hazard. Your perspective on 'safe boating lanes' changes completely when the lake rises as much as some of these have.
