...You might want to think about possible sunscreens for shade, maybe even to cut maximum insolation in the hottest months
I actually have enough floating islands to cover over half of the surface area of the pond. That would do the trick, right? That brings me to another question, in addition to the liner question posed above. If I make the slopes steep enough, will I have to worry about herons? And also, will great blue herons feed off of a floating island? That could be a potential problem. I'd hate to have to buy an individual MJ for each island.
