Oh clarification the hole/pond has never had less then 5 feet of water even in the worst summers we have had here (I think it was driest in 70 years) the hole had a minimum of 5 feet of water but since winter melts its been at full capacity , it's over flowing on the lowest side actually but I have a trench and that's all good. But I am thinking of building up the lower side more to have more water and I was considering making shelves to make the plants easier to figure out. But I'm thinking with out a source to replenish that almost 10 foot drop of water would kinda make it hard on the plants. I may have to watch what happens this summer .
