Irrigation canals that are still in use today.

They irrigated, but in very dry years, especially the 200 year long drouth that drove the Anasazi and the Chaco cultures out of the 4 corners area, the Hohokam used "Rock Mulch Agriculture". If you look on the tops of mesas, you will find little rocks that are not native to the mesa tops. The Hohokam brought those up from the valley floor and you can still see their 'gardens' today.

They discovered, as did the other Pueblo People, that they could sow their seeds under little rocks and that would not only provide moisture for the seeds to germinate and grow, but protect them from the birds until they had sprouted.

The Mesa tops in that whole part of Arizona and New Mexico are covered with the ancient Rock Mulch fields...

very long irrigation canals and an ingenious lock/dam system that allowed the water to get into all the fields
they would have one major irrigation canal that would feed all the others with dams that they could open and once that field had the necessary water, they could close that dam and allow the water to continue to the next dam and repeat the process until all fields were done.
