 During the 1960s hydraulic development shifted towards multi-purpose dams, returning to canal network development for the next 30 years and reaching the current 280,000ha equipped with irrigation infrastructure.The Irrigation Management Transfer Program (IMTP) started formally in the mid-1980s and continues until today.IMTP aims at decentralizing operation and maintenance, and fee collection responsibilities among others to the "Juntas de Regantes" (Water Users Irrigation Boards - WUB).
