I just realized I have been contemplating a raised sides pond because I love tree frogs. We used to have them in our above ground pool but since adding an inground we don't get them anymore and I miss seeing them. I read up on it a little and I need the sides at least 6" off the ground, more would probably be better. I was thinking of hiding the sides with rocks so it would look more natural. I'd imagine I'd have to make it completely seperate and maybe during large rain storms it would overflow to it. Another idea I have is the raised area could maybe be like a waterfall basin to pour into a ground level area. Not sure if the tree frogs would like water moving though. I'd imagine it would disturb their eggs.
