Resumen
Between the thirties and the fifties of the 20th cent., some Valencian irrigators communities agreed to do not passively accept the government policies of water regulation. The trustees of the Acequia Real ?the most important and complex irrigation entity at the Júcar basin? led this dynamic between hydraulic interventionism and ?peripheral? reactions. They experimented new forms of internal administration as well as collaboration with the other traditional users of the basin; they worked as stakeholders of the ministers of Public Works. In this sense, the Acequia Real del Júcar is suited to an analysis of the institution and even of the process that drove it to be head of lobbing group at different scales that defended their interests in the rivers.
