And not a little more water, no. Much more. Because, let’s be honest, since 1979, when the transfer was opened, the Entrepeñas and Buendía reservoirs so much accumulated water has never been seen there: we are talking about reserves of 1,649 hm3.
On the other hand, a little further to the southeast, the entire Segura basin has 52 hm3. That is, an almost exact third.
These are just a couple of pieces of information, but they are enough to explain why, although the Community Board of Castilla La Mancha sue the Central Government180 hm3 of water from the Tagus will end up in the Segura before the end of the quarter.
On autopilot. On March 13, 2026, the Central Transfer Exploitation Commission approved that shipment. The current regulations do not give much room for maneuver: the headwaters of the Tagus entered Level 1 months ago and that, with the current rules, means activating the transfer of water resources.
The problem is that the rules have been out of date for years and, in fact, the proposed modification (more favorable to the interests of the Tagus) has been stalled in the Supreme Court for months.
And it is still curious that rules designed for a scenario with little water generate problems, precisely, when there is more water.
What does Castilla – La Mancha complain about? The most obvious thing is that the Government is manifestly failing to comply with the Royal Hydrographic Planning Decree: According to the text, the new regulations were to be in force in February 2024. That is, we are two years late.
And this delay is not innocuous: the Board maintains that the current rules do not ensure the environmental protection of the Tagus or all the associated Natura 2000 network spaces. At the end of the day, they point out from Toledo, what the Exploitation Commission has approved “it wastes 11% of the impounded water” at the head of the river.
And what happens in Murcia? We already said months ago that Murcia (and the southeast in general) They had already assumed that depending on transfers It was something very committed. It is true that the expansion of some desalination plants has been approved and is working in construction from others, but the tenders are very slow.
This time gap is not only a problem for irrigators, it is a ticking bomb for the different administrations involved. After all, the elections are just around the corner.
What can we expect? This is the simplest part of the matter: as long as the Supreme Court does not get its act together or the Ministry decides to take action on the matter, the transfers will continue to occur automatically “as if nothing had happened.” That is to say, the irrigators of the Segura are going to win (again and again) over the riverside municipalities of the Tagus.
It doesn’t matter how much politicians stage things. The conflict between regions is in the very core of the country: in the water that runs through its ‘veins’.
