Descripción:
The Miguel Alemán reservoir was built in 1957, destroying the habitat of the mazateca culture, which was separated from its original land, to which little by little those who did not adapt to their new home returned, but are now facing a different sociocultural situation, with new sectors, economic groups and factions, which would enter the political arena in later years. This document follows-up the evolution of the populations of the reservoir (since it was built until the decade of the eighties) from an economic variable which arose from fishing, up to today social and political organization.
