The reservoirs are almost 22% above the average of the last decade. There is an “but” important before celebrating

The forecasts of meteorologists seem to indicate that spring You have your days counted: Next week we will see an increase in the temperatures and models of the State Metorology Agency, they foresee that in the middle of June the rainfall is less than what is usual for these dates.

Despite this, this short spring has been intense, and that It has been reflected In the reservoirs.

77.5%reserves. The latest data indicates that the water reserve has been placed this week at 43,407 cubic hectometers (HM³), 77.5% of its capacity. As it stands out The Ministry for Ecological Transition and Demographic Challenge, to this have contributed “abundant” rainfall in the Peninsula and especially in Lugo, where 55.8 mm have been reached.

The internal basins of the Basque Country (95.2% of its capacity), the Duero (92.6%), and the western Cantabrian basins (92.2%) They are the ones closest to their theoretical maximum. In the south stands out The River Basin Odiel, red and stonesat 91.7% of its capacity.

Almost 22% more than average. We have been more than a year in which the reservoirs accumulate more water than the average of the previous 10 years. The current 43,407 hm³ represent an increase of 21.79% above the average of the past decade, 35,641 hm³.

It is good news, but it should be remembered that the data of the Decenal has been significantly weighed by last decade. If we go To data from five years ago, we will see that the average filling of the previous ten years (2010-2019) was 74.3% global and 71.8% if we focus on the reservoirs of consumptive use. The average of the last 10 years is now quite far, in 63.7% for the set of reservoirs, and in 58.1% if we focus on consumptive use.

Unequal state. As usual, there are marked differences in the filling level of the different basins. We indicated before some of those that are closest to the full filling, all of them above 90% of their capacity. At the other end, the southern and southwest basins remain at relatively low levels, highlighting the safe basin, at 31% of its capacity.

The positive reading is that even this basin has seen its level of filling in recent months. This last week, in fact, the basin has seen an increase of almost 1% compared to the previous week. The Andalusian Basins of the Mediterranean, also among the most empty, have also experienced a slight increase in their volume, until approaching the 57.6% of its capacity.

The negative note is put by the Guadalete and Barbate basin, the second with the lowest average filling (at 54.88%), which has lost six Hm³ in recent days, a reduction of 0.36%. Of course, the basin shows a markedly superior filling last year by these dates (30.28%) and also slightly higher than the average of the last 10 years (53.31%).

The end of spring. The state of the reservoirs allow us to face with slight optimism an uncertain and imminent summer. Meteorological forecasts They point out a drastic increase in temperatures in the next few days, and not just that.

Aemet’s medium -term predictions also indicate that the trend of the coming weeks will not only point to warmer temperatures than usual by these dates, but also towards precipitations below average. This seems to imply the end of spring, at least from the meteorological point of view, and the beginning of a summer that we do not know what will hold us.
