According to data from the National Water Resources Information System (SNIRH) available today, the western Algarve river basin rose from 20.7% at the end of February to 35.6%, data up to March 10.

Also in the south of the country, the Mira river basin rose from 40.4% (at the end of February) to 45.4% (on March 10) and the Arade river basin from 41.8% to 50%.

Still in the Algarve region, where restrictive measures are in force for water use, the Sotavento river basin was at 86.8% on March 10.

According to SNIRH, in the first week of March (from March 3 to 10), 69% of the monitored reservoirs had water availability greater than 80% of the total volume and 5% had availability less than 40%.

In the first week of March, storage by river basin was higher than average, except in the Ave, Mondego, Mira, Arade and Ribeiras do Barlavento basins.

The amount of stored water fell in two river basins and rose in 13. Each river basin can correspond to more than one reservoir.
