The Andalusian reservoirs increase their water reserve to 18.9% after 19 weeks of decreases, due to the rainfall of recent days, specifically, they have 51 cubic hectometers (hm3) more -2,115– compared to the previous week, when they were at 2,064. This 18.9 percent water reserve is three percentage points lower compared to the previous year, when, with 2,448 cubic hectometers, the Andalusian reservoirs were at 21.9 percent.
According to data offered on Tuesday by the Ministry for the Ecological Transition and Demographic Challenge, in the last week, the water stored in the reservoirs of the Guadalquivir basin rose half a tenth to 18.4 percent with a total of 1,476 hectometers cubic, while that of the Andalusian Mediterranean Basin drops 0.3 tenths to 22.2 percent, with a total of 261 hm3.
These are the two main reservoir systems in Andalusia. The others are Tinto, Odiel and Piedras in Huelva, and Guadalete-Barbate in Cádiz. The reservoirs in Huelva rise by eleven cubic hectometers to 128, with their reserves at 55.9 percent of their capacity, and those in Cádiz remain the same as last week, with 250 hm3, and standing at 15.1 percent.
At the national level, the current total capacity of the reservoirs has increased this week by 1.0%, so the Spanish water reserve is at 35.6% of its total capacity, increasing by 577 cubic hectometers (hm3). In this way, the recent rainfall has managed to stop the downward trend of recent weeks.
The reservoirs currently store 19,945 hm3 after a week of rainfall that has considerably affected the entire Peninsula. The maximum occurred in Vigo, with 233.7 liters per square meter (l/m2).
By areas, the reserve in the Eastern Cantabrian Sea is at 75.3%; in the Western Cantabrian Sea, 71.2%; in Miño-Sil, 57.1%; in Galicia Costa at 62.1%; in the internal basins of the Basque Country, 66.7%; in Tinto, Odiel and Piedras, at 55.9%
Below half are the Tagus, at 47.6; the Duero, at 42.7%; Júcar, at 46.8%; Ebro, at 34.7%; Guadiana, at 24.3%; Safe, at 22.3%; Andalusian Mediterranean Basin, at 22.2%; Internal basins of Catalonia, at 19.9%; Guadalquivir, at 18.4% and Guadalete-Barbate, at 15.1%
