Poyo River: Flow Surges from 29 to 1,686 m³/s in Under Three Hours

From 'falling flow' to disaster: the timeline of the emails

How do you go from a warning that the river is receding to one describing a flood capable of wiping out half the region? Between the two, there are two and a half hours, a graph missing a zero, and a mobile alert that did not sound until much later. The timeline of the emails from the Júcar River Confederation (CHJ) during the DANA (Depression in the Upper Levels) that hit the province of Valencia has become the heart of the issue. At 16:13, an email informed of the 'falling flow' in the Poyo ravine: at 15:50, 29 cubic meters per second had been measured, below the 30 that trigger the first threshold, and the trend was downward. At 18:43, another email described the unthinkable: 1,686 m³/s, more than eleven times above the 150 that mark threshold 3.

What the 18 emails between 16:13 and 18:43 contain

The report accessed by the press counts 18 emails sent by the Confederation within that interval. Only two refer to the rise in flow; according to the reading that has been disseminated, the rest repeats the downward trend. The first serious warning, with a flow of 264 m³/s, triggered an apparently automatic alert from 112 and was addressed to Valencia's Civil Protection. The trinc messages repeated recipients and tone, almost as a formality. Until at 18:43 everything breaks: the flow multiplies and the list of recipients changes. Anyone looking at the complete sequence understands why the word 'negligence' has ceased to be a hypothesis.

The graph with one missing zero that divided the flow by ten

The Confederation itself acknowledged the error. In response to a user asking if the graph did not carry an error—the maximum seemed to mark 200 when in reality it was 2,000—the agency replied that 'indeed, there is a missing 0 in the flowing flow values' and lamented the error. Translated: for hours, the data circulating among officials arrived divided by ten. Some emphasize that before 18:00 the flow had already exceeded 400 m³/s when the warning limit was 150. That is: the figure that should have triggered all alarms was already on the table, only disguised by a missing zero.

Why the mobile alert did not arrive until 20:10?

The email describing the catastrophe was sent at 18:43, but the mass message to the population was not sent until after 20:00. The gap between these two moments sustains the version that the negligence was not two hours, but one. If all previous communications spoke of a decline, it is possible that the last email was not read until after 19:00. What remains unanswered is why no one warned of the brutal rise between 18:00 and 18:43, when the data was already speaking.

Who was warned and the knot of competencies

The least discussed but most relevant detail lies in the recipients. According to the analysis of the emails disseminated, the 18:43 email removes Valencia's Civil Protection from the list and places the Government Subdelegation and the communication office of the Government Delegation in its place. The alert flew primarily to the central administration, while those with management competencies were the autonomous government. Some argue that the division of powers is a factory of perfect excuses: responsibility is always 'someone else's'. This mismatch explains why each side points to the other without entirely failing to tell the truth.

The battle of the narrative: Aemet, Mazón, and crossed blames

The crossing of versions is total. One part points out that Aemet (the Spanish State Meteorological Agency) had communicated that the rains would cease, which relaxed decisions; another recalls that the head of the Confederation is a former socialist councilor and that the direction of Aemet in Valencia is related to the central government. On this board, cross-accusations are launched between the Government and the Generalitat. The basin's data, meanwhile, trinc its own course, indifferent to political marketing. An alert designed to save lives ended up becoming campaign material.

Flows, branches, and dams: the front almost no one looks at

Outside the noise lies the terrain. Some recall that the river confederations have been banning the cleaning of branches in waterways for years, which favors logs and debris blocking the flow of water and causing sudden bursts. Others point to a natural damming of vegetation that may have broken loose suddenly and explained the jump in flow. Along the same lines, the Buseo Dam on the Sot River, a tributary of the Turia, is highlighted, which would have suffered overflows and been left with a huge sustancia ilegal without warning the population. These are hypotheses requiring technical review, not urgent headlines.

With these threads, it is not strange that no one has resigned. It is strange to continue believing that the problem was an email sent at 18:43 and not an entire system that makes hundreds of lives depend on someone checking their inbox.
