In 1971 the Waimiri Atroari Indigenous Reservation was created, however between plans for Amazonas expansion and the discovery of cassiterite deposits, the government continued to infringe on the land (Do Vale). The reserve was demoted to a Temporary Restricted Area for the Attraction and Pacification of the Waimiri Atroari Indians in 1981 in order to exclude the mineral deposits from their land (Do Vale). Later more land was taken from the Waimiri Atroari as a hydroelectric plant project flooded over 30,000 hectares of their land (Do Vale). Today the Waimiri Atroari have their own school system which they control independently (Do Vale).
