Answer:
Taking advantage of the natural path of the waters, the natives built small fences, which are canals dug in the earth. They carried river water to houses and crops using only the force of gravity. A lot of acequia that exist to this day. They would settle next to an acequia and use that water to grow beans, squash, potatoes, tomatoes, and corn.
The Spanish not only preserved but improved the use of de water. In the old days, the acequia ran everywhere, cut streets, disrupted people's lives. Today, in every city in the province, they run along the sidewalks and bring water directly to the roots of the trees used to plant streets, squares and parks.
