Lake Chalco

Lake Chalco itself had a fresh water hydrologic structure due in large part to the artesian springs lining its south shore.

However, this growth was not due to Lake Chalco inhabitants discovering chinampa techniques, as they existed on a limited scale from 300–1350 AD.

[4] The Aztec empire, led by King Itzcoatl conquered the Southern region (Lake Chalco and Xochimilco) and used this area for chinampa development.

[4] The Aztec Triple Alliance needed large amounts of foodstuffs to maintain the growth of Tenochtitlan and the control of other communities through tribute; therefore, they conquered lands optimal for chinampa farming.

A land speculator's draining of the lake in the late 1860s led to a tenant farmer (campesino) revolt organized by Julio López Chávez that was eventually put down by the federal government.
