Key details
As of December 2, 2025, water reservoir levels in Spain have reached 53.80% capacity, marking a modest weekly increase of 0.38%, with total stored water at 30,148 hm3, according to the latest Hydrological Bulletin from the Ministry for the Ecological Transition and the Demographic Challenge (Miteco). This reflects a growth of 213 hm3 compared to the previous week and shows an improvement from last year's 51.14% capacity when reservoirs held 28,660 hm3.
Significant regional differences remain evident across the country, with Catalonia maintaining the highest reservoir capacity at 72.67%, while Murcia continues to face challenges having only 22.97% capacity. These regional variations highlight the ongoing need for targeted water management strategies.
Miteco has reinforced the importance of monitoring reservoir levels to manage water usage responsibly and has released specific recommendations for households to conserve water, especially in bathrooms. Suggestions include preferring showers over baths, installing efficient showerheads, limiting shower time, using toilet cisterns wisely, and repurposing water collected while waiting for it to warm up.
This latest data emphasizes the critical state of water resources in Spain as winter precipitation patterns impact reservoir recharge. Continued vigilance and adoption of conservation measures remain crucial to ensuring sustainable water availability moving forward.
