They evolved to be quite dependent on the unique agricultural islands in the Valley of Mexico called Chinampas. These were drained by the colonizers. Which is why Mexico City is now facing a severe water crisis and also why these creatures are endangered

Lake Texcoco was only partially drained by the Spanish. The big project to drain the lake was undertaken by President Porfirio Díaz in the early 1900s.
