Step 1: About the Aztec Water Garden
In reality, it is a garden that is supported by pylons. This is a drawing I made of an Aztec water garden. It is actually called a Chinampas.
The benefits of growing a Chinampas garden are: they provide shelter for the pond fish against predators, and vegetables grow healthier, and the vegetables yield 7 times more crops.
The next picture is a modern day Chinampas.
