Overview
- Official hydrographic data for the week of Sept. 8–14 show total stored water in Spain at 33,801 hm³, a 1.2% fall from the previous week and equal to 60.3% of reservoir capacity.
- Galicia’s consumptive reservoirs lost 11 hm³ over the week and now hold 300 hm³, with the Miño‑Sil demarcation slightly above its ten‑year average and Galicia‑Costa below it.
- The Tajo head reservoirs Entrepeñas and Buendía fell by 9.73 hm³ and together store 1,280.31 hm³, or 50.84% of their combined capacity, with Entrepeñas at 488.05 hm³ and Buendía at 792.26 hm³.
- Most individual reservoirs in the Tajo head declined, notably Alcorlo which lost 2.11 hm³ and now holds 98.44 hm³, while Almoguera and Bolarque recorded small weekly gains.
- The weekly bulletins distinguish total stored volume from water earmarked for consumption and are the basis for regional supply decisions, so continued week‑to‑week drops will guide allocations and drought assessments.
