They hold 328 million cubic metres of water, 13 million more than a year ago, Postal reported, citing figures supplied to Lusa by the Portuguese Environment Agency (APA).

APA president José Pimenta Machado welcomed the improvement but warned that water-saving measures and investment must continue. He said the region has water available, but cannot afford to waste it.

Supply networks

Reducing losses from urban supply networks and agricultural irrigation systems remains a priority.

The planned desalination plant would provide another source of water, less dependent on rainfall, while the connection between Pomarão and the Odeleite reservoir would help strengthen supply.

Pimenta Machado said these projects should advance while reserves are healthier, allowing the Algarve to prepare before another period of scarcity.

He also called for efficient water use across households, tourism, agriculture and services.

These figures refer to 28 September.

Hydrological period

Portugal’s hydrological year runs from 1 October to 30 September, beginning as the rainy season approaches.

October to April is generally considered the wet period, followed by the drier months from May to September.
