Positive Water Balance in the Basque Country During the 2024-2025 Hydrological Year

The Basque autonomous community has experienced a notable increase in rainfall during the current hydrological cycle, reaching approximately 810 liters per square meter accumulated by spring, a figure that significantly exceeds the 710 l/m² representing the historical average for this period 🌧️.

Territorial Distribution and Annual Comparison

When contrasted with the previous year, a more regular and balanced rainfall pattern is observed across the entire Basque geography. This homogeneous distribution has made the region one of those with the greatest water surplus in the country, guaranteeing abundant reserves for the coming months and reducing the need for external contributions 💧.

Main Characteristics of the Rainy Season:
  • Rainfall episodes more frequent and prolonged than in previous years
  • Accumulations exceeding the established historical average by 100 l/m²
  • Territorial uniformity in the distribution of precipitation
The regularity of the rains has consolidated the Basque Country as a benchmark in water management during this cycle

Consequences for Resources and Productive Sectors

This rainfall surplus has had a direct and beneficial impact on the availability of water resources. The main reservoirs and aquifers show optimal storage levels, ensuring a stable supply for domestic consumption and favoring the agricultural and industrial activities of the community 🏭.

Highlights of the Positive Impact:
  • Complete recharge of aquifer systems and riverbeds
  • Guarantee of urban supply without restrictions
  • Boost to agricultural productivity and industrial activities

Considerations on Management and Prevention

Despite the overall favorable balance, authorities maintain surveillance protocols in areas with a history of flooding, implementing preventive measures to minimize risks associated with possible localized overflows and waterlogging. While some citizens joke about the need to incorporate umbrellas and rain boots as basic elements of spring attire, experts emphasize the importance of maintaining responsible management of water resources ☔.
