Before an autumn that is expected to be warm, along with some reservoirs well below its total capacity, the water deficit is aggravated in almost all of Spain especially in the south, and despite the fact that in basins such as the Duero, Ebro and Tajo they already perceive signs of serious shortage, the situation is not limit.
There are reasons to "start worrying," although "we are not in an extreme situation," because a rain probability period is approaching and "there will be a very direct and timely monitoring" in each system, supply and basins, he explained Professor Alberto Garrido, director of the Water Observatory.
"We are entering a situation that can be aggravated, or that can be resolved," he added.
According to the historical records of the Ministry for Ecological Transition (Miteco), the Duero basin is currently at 41.3% compared to 53.4% in the 2019-2009 period, while that of the Tagus, is at 34, 7 versus 48% of the average for the decade.
Another of the basins with a significant decrease in their total capacity is that of the Ebro, which is currently at a level of 45.3 percent, seven points below 52.16 percent in the period 2019-2009.
The peninsular average stands at 40.4 percent, 13 points below the average for the decade, 53.4 percent, according to data.
In addition to the Tagus, the most precarious basins – with levels below 40 percent – are: Segura (27.6%), Júcar (30.1%), Guadalquivir (35.1%) and Guadiana (38.3% ).
Gonzalo de la Cámara, academic director of the Water Economy Forum and advisor to the European Commission on Water policies, recalled that seven of the ten basins in Europe with the greatest water stress are in Spain, and that of Segura is the worst from all over Europe, according to data from the European Union (EU).
"It is a dry year," said de la Cámara to emphasize that the problem is the structural shortage of water that persists in Spain, beyond which there may or may not be drought, because the main thing is that "in areas of Spain always there is a chronic and long-term water shortage. "
On the opposite side of the previous basins, in terms of the amount of reservoir water, according to Miteco data, those of the Cantabrian and the Basque Country stand out, with levels between 62.5 and 71.2%, and Galicia, with almost 60 percent in the Miño zone and 65% in the coastal zone of the region.
By communities, Castilla y León, with severe problems already lacking water in the province of Ávila, the total water stored ten years ago amounted to 4,357 cubic hectometers, compared to 3,412 current hectometers, eleven points less.
In the Community of Madrid, the total capacity of its swamps is 1,060 cubic hectometers although they currently store 524 cubic hectometers, 300 less than in the same week of ten years ago, after having gone from 66.7 percent to 49, 4 %.
According to Professor Emeritus Ramón Llama, a member of the Royal Academy of Science, it is "a big mistake" to consider only water stored in surface reservoirs and not to take into account that of aquifers, because these are essential in times of drought , "provided they are in good quantitative, qualitative and not over-exploited state".
In the case of the Valencian Community, and according to data from the Miteco, despite the heavy rains after the episode of cold drop or DANA – isolated depression at high levels – that affected the peninsular southeast last September, the amount of water accumulated is of 714 cubic hectometers versus a capacity of 2,447 hectometers.
In the Region of Murcia, however, the effects of DANA have been noted and its reservoirs are almost 44 percent, 18 points above the levels of the last decade.
