Thanks to recent rainfall, Spain has seen an overall increase in reservoir levels. However, three key regions in the southeast—Murcia, Andalucia’s Mediterranean basin, and the Júcar basin—are still experiencing declining water reserves.
Since October 1, these areas have seen a steady drop in reservoir levels, according to data from the Spanish State Meteorological Agency (AEMET).
Murcia most critical
The Segura basin in the Region of Murcia is suffering the most from water shortages. Its reservoir capacity is filled just 14.6%. Since the start of the hydrological year, the region has received only 13 litres of rainfall per square metre. A number far below the average of 317 litres over the past five years. The current water reserves in the Segura basin stand at 166 hectometres. That is a significant drop from last year’s 254 and far below the 352 hectometres typical for the past decade.
In response, the Segura River Basin Authority (CHS) has maintained existing water restrictions, limiting irrigation by 40% for traditional users and 57% for non-traditional users. The restrictions for rivers on the right bank of the Segura have also been doubled. Furthermore, water intake gates will be closely monitored to ensure compliance.
Andalucia and Valencia also struggling
The Mediterranean basins in Andalucia, including areas of Málaga, Almería, and Granada, are similarly affected. These regions have lost 13 hectometres of water since the start of October, with reservoirs currently at 21.9% capacity. This is lower than the levels seen last year and significantly below the average for the last decade.
The Júcar basin, which covers much of Valencia and parts of Castilla-La Mancha, is also facing water shortages. The basin holds 1,140 hectometres of water, a decrease of 25 hectometres since the beginning of October, and is 192 hectometres below the levels recorded this time last year.
Uneven relief across Spain
While these regions continue to struggle, other parts of Spain have seen significant improvements. For instance, Andalucia’s reservoirs overall have risen to 30% capacity, with an increase of 168 hectometres in water reserves. However, the situation remains uneven across the region, with some provinces, like Málaga and Almería, seeing water levels as low as 7% and 15% of capacity, respectively.
