Overview
- The Xunta placed the Ulla‑Tambre and Costa Norte river systems in 'sequía prolongada' after measurements showed a sustained fall in rainfall and natural water resources on Thursday.
- The status does not impose immediate consumption bans but allows the Galicia‑Costa hydrological plan to lower ecological flow requirements for rivers when needed.
- The Oficina Técnica da Seca kept 32 municipalities in 'alerta' with mandatory conservation duties and moved nine territorial units into 'prealerta', leaving 95 municipalities under intensified monitoring.
- Local councils in 'prealerta' must report daily water‑use data to Augas de Galicia and municipalities in 'alerta' may restrict nonessential uses such as street washing, garden irrigation and pool filling or apply short supply cuts.
- Reservoirs serving the Galicia‑Costa demarcation stand at about 52.34% capacity, nearly 13 percentage points below the same date in 2025, and officials say shifts from prealerta to alerta will be the next signal to expect stricter measures.
