Question

What kept the soil of the chinampas from oozing into the canals? What anchored each chinampas plot to solid ground beneath the water level ?

Answer 1

The island was built on reed frames, which keeps the soil oozing into the canals. The roots of the plants on the chinampas also help hold the soil together.
