The reservoirs of Andalusia have recorded a significant increase in their volume of stored water over the last week, reaching a level of 55,77% of its full capacityThis was reported by the Andalusian Government Council after learning of the weekly balance, which reflects a sum of 1.183 cubic hectometers (hm³) more than previous data. This increase represents an improvement of the 9,89% in just seven days.
The current volume of the reservoirs of Andalusia It amounts to 6.673 hm³, which represents an rsubstantial recovery compared to the same period last year. Specifically, there are 3.175 hm³ more than in March 2024, and 733 hm³ above the average of the last decade. These data are due, in large part, to the intense rainfall recorded between the March 12 and 19, 2025, which have favored the recharge of the main hydrographic basins of the autonomous community.
The Guadalquivir basin leads the recovery of Andalusia's reservoirs
Among the most benefited hydrographic demarcations is the Guadalquivir, which currently accumulates 4.527 hm³ of water, located at 56,38% of its full capacityThis data reflects an increase in 816 hm³ compared to the previous week, that is, a growth of 10,16%. In addition, the current volume is 2.123 hm³ more than last year y 686 hm³ higher than the average of the last ten years.
Brianda Andalusian Mediterranean Basins, reservoirs of Andalusia have reached the 49,53% of its capacity, with 571 hm³ stored after an increase in 91 hm³ in the last seven days. This volume represents 312 hm³ more than in 2024, which also reflects a positive evolution compared to the average of the last decade.
General increase in the rest of the hydrographic districts of Andalusia's reservoirs
The demarcation Guadalete-Barbate, located in the province of Cádiz, has experienced a notable increase in its water resources. reservoirs of Andalusia in this area they accumulate 801 hm³, 48,51% of its full capacity, after adding 167 hm³ in a week. This volume is 452 hm³ higher than the same date in 2024, although still 40 hm³ below the average of the last decade.
In the basin Red-Odiel-Piedras-Chanza, reservoirs of Andalusia they store 774 hm³, which represents the 69,42% of its capacity, after an increase of 109 hm³ in one week. In year-on-year terms, the demarcation has 288 hm³ more than in March 2024 y 63 hm³ above the average of the last seven years.
Regarding other basins that partially affect the autonomous community, the demarcation of the Guadiana is at 56,35%, with 5.375 hm³, after an increase of 522 hm³ in a week. This means 1.646 hm³ more than in 2024 and a volume 694 hm³ higher than the average of the last decade.
In contrast, the basin of the Segura maintains lower levels, with 279 hm³, which means the 24,47% of its full capacity. Despite having added 22 hm³ in the last week, it is still 125 hm³ below the average of the last ten years, although 57 hm³ above the level recorded on the same date in 2024.
Heavy rains are driving up reservoirs in Andalusia, forcing controlled releases.
The increase in the level of the reservoirs of Andalusia It is a direct consequence of the heavy rains recorded in mid-March in different parts of Andalusia. They have been reached 282 liters per square meter (l/m²) in Grazalema, 270 l/m² in Jimena y 203 l/m² in the Sierra de Luna, all of them in the province of Cadiz. Malaga has also seen important records, such as 228 l/m² in Tolox, 208 l/m² in Ojén y 204 l/m² in Casarabonela.
In the province of Seville, the following stand out: 224 l/m² in the José Torán dam (Lora del Río) and 132 l/m² in Peñaflor and in the La Minilla Dam (El Garrobo). Córdoba has reached 234 l/m² in Martín Gonzalo (Montoro) y 206 l/m² in Castro del Río, while in Granada they have been registered 205 l/m² in Molinillo (Huétor-Tájar)Huelva and Jaén have also contributed significant figures, exceeding in both cases the 150 l/m².
These heavy rainfalls have forced the Government of Andalusia to carry out controlled discharges in several dams to ensure the safety and proper functioning of the hydraulic systems. In the Andalusian Mediterranean Basins, water resources have been relieved in the dams of The Conception, Count of Guadalhorce, Casasola and Béznar. In the demarcation Guadalete-Barbate, floodgates have been opened in the dams of The Hurones, Bornos, Arcos and Almodóvar (Tarifa). Likewise, in the basin of the Red-Odiel-Piedras-Chanza dams have been released from the reservoirs of Piedras, Los Machos, Corumbel, Sotiel-Olivargas, Jarrama and Cueva de la Mora.
The Andalusian Government is putting out to tender the renaturalization of the Palmones River in Cádiz.
In addition to the management of the reservoirs of Andalusia, the Governing Council has announced the Tender for the renaturalization works of the Palmones River, located in the municipality of Los Barrios, in the province of Cádiz. The intervention has an initial budget of almost 2,7 million euros and an estimated execution period of 12 months.
The Andalusian Government's goal is to mitigate the risk of recurring flooding in this town, caused by the degradation of the Palmones River. The project, promoted by the Regional Ministry of Agriculture, Fisheries, Water and Rural Development, includes nature-based solutions to Increase the resilience of Los Barrios to flood events.
Among the planned actions, the following stand out: construction of a 2,6-kilometer river trail a cycle-pedestrian walkway which will connect both banks of the river, the removal of eucalyptus stalks, recovery of native plant formations of riverbank and the improvement of the canoeing dock.
This project is aligned with the Andalusian Government's strategy of sustainably manage water resources and river ecosystems, in addition to promoting the orderly public use of natural space.
