Andalusian reservoirs drop 0.21% in a week but hold 3,134 hm3 more than in 2025

Andalusia's reservoirs store 8,285.61 cubic hectometres of water, which represents 69.34% of the total storage capacity, set at 11,948.63 cubic hectometres. In the last week they have lost 24.85 cubic hectometres, 0.21%, according to the report from the Regional Ministry of Agriculture, Fisheries, Water and Rural Development, which the Governing Council has taken note of. The weekly drop does not change the comparison with last year: the water accumulated now is 3,134.54 cubic hectometres more than on the same date in 2025 and 3,987.09 more than the average of the last ten years.

In the Guadalquivir basin, stored water falls by 10.97 cubic hectometres in seven days (-0.14%) and stands at 5,510.68 cubic hectometres, 68.57% of its capacity. Compared with the same date in 2025, the basin gains 2,196.14 cubic hectometres, and 2,819.92 against the decade's average. The Andalusian Mediterranean Basins are at 64.6%, with 739.36 cubic hectometres, after losing 3.45 in the last week (-0.3%). They exceed last year's figure by 221.5 cubic hectometres and the last decade's average by 291.84. Guadalete-Barbate accumulates 1,232.51 cubic hectometres (75.65%) after reducing its resources by 2.33 cubic hectometres in seven days (-0.14%). The trend is positive compared with the same week of 2025 (+547.9) and with the average of the last ten years (+625.57). In the Tinto-Odiel-Piedras-Chanza basin the water falls by 8.1 cubic hectometres (-0.71%) and leaves the total at 803.16 cubic hectometres, 70.51% of the demarcation's capacity. That is 168.56 cubic hectometres more than on the same date in 2025 and 249.76 more than the average of the last eight years.

The figure does not involve any procedure for residents: it is a status report that the Governing Council has taken note of and that is updated every week.
