The amount of water stored decreased in June in all basins compared to the last day of the previous month, according to data from the National Water Resources Information System (SNIRH).
The Barlavento Algarve basin remains the one with the lowest amount of water reserves, going from 22.3% in May to 20.8% in June.
At the end of June, the Mira basins also had lower water availability (41.4% in May) and Arade 40.8% (42.7% in May).
The amount of water also decreased in the Lima basins, from 76.1% to 53.5%, and in the Sado basin, from 72.3% to 66.7%.

According to data from SNIRH, of the 58 reservoirs monitored, 28 had water availability greater than 80% of the total volume and another six below 40%.
You June 2024 storages by river basin are higher than June storage averages (1990/91 to 2022/23), except the Lima, Mira, Ribeiras do Algarve and Arade basins.
Each hydrographic basin may correspond to more than one reservoir.
According to the Portuguese Institute of the Sea and the Atmosphere (IPMA), almost half of the territory of continental Portugal was experiencing a weak or moderate meteorological drought at the end of May, with the greatest concern being in the southern region.
