The volume of stored water fell in all of Portugal’s monitored river basins, according to data from the National Water Resources Information System (SNIRH) for the last day of August.
Of the 60 reservoirs monitored, 11 had water availability of more than 80% of their total volume and 19 less than 40%.
According to the SNIRH data available today, the Barlavento (8.4%), Sado (21.8%), Arade (28.6%) and Mira (31.8%) basins had the lowest water availability at the end of August.
The Lima basin had the largest volume of water, 86.3% of its capacity, followed by the Douro (79.6%), Cávado (78.7%) and Ave (76.9%).
August 2023 storage by river basin was generally higher than the August storage averages (1990/91 to 2021/22), except for the Sado, Guadiana, Mira, Ribeiras do Algarve and Arade basins.
Each river basin can have more than one reservoir.
