Water War Intensifies Over Trasvase

Valencia and Murcia closed ranks on April 27 to defend the Tajo-Segura water transfer at a SCRATS rally in Pilar de la Horadada. (europapress.es) (elpais.com) Valencian president Juanfran Pérez Llorca and Murcian president Fernando López Miras used the event to demand an “immediate” halt to new operating rules for the transfer. (europapress.es) The Tajo-Segura transfer moves water from headwater reservoirs on the Tagus River toward Murcia, Alicante and part of Almería, where irrigated farming and urban supply depend on it. (miteco.gob.es) (elpais.com) The immediate trigger is twofold: Spain raised the Tagus ecological flow at Aranjuez to 8 cubic meters per second on January 1, 2026, and the ministry is still weighing a broader rewrite of transfer rules. (laopiniondemurcia.es) (europapress.es) Those rules decide how much water can be sent depending on reservoir levels in Entrepeñas and Buendía, the two headwater dams that feed the aqueduct. (miteco.gob.es) The Environment Ministry said on April 14 that it will wait for pending Supreme Court rulings before updating the rules, after Castilla-La Mancha challenged the government over what it called inaction. (europapress.es) That legal pause has not lowered the political temperature. Castilla-La Mancha argues the transfer should keep shrinking and has pushed desalination as the alternative for the southeast. (elpais.com) On the other side, López Miras and Pérez Llorca say Spain has enough water overall and that sending more flow down the Tagus while cutting the transfer hurts farms in Murcia, Alicante and Almería. (elpais.com) (europapress.es) SCRATS, the irrigators’ syndicate that organized Monday’s event, has been trying to widen the fight beyond farmers and turn it into a broader public campaign. (europapress.es) (larazon.es) For now, the transfer remains in level 2, which the ministry described in January as “normal hydrological” conditions with 1,014.1 cubic hectometers stored in the headwaters. (miteco.gob.es) The next move is not in Pilar de la Horadada but in Madrid: court rulings and any ministry decision on the rules will determine how much Tagus water can keep reaching Spain’s southeast.
