According to the weekly bulletin on reservoir storage,
published by the APA on Tuesdays with data from the previous Monday, of the 79
monitored in mainland Portugal, 48 had a storage volume between 81% and 100%.
Thirteen basins had a capacity between 61% and 80%, six
between 51% and 60%, two between 41% and 50% and seven between 21% and 40% of
the total volume, and three with less than 20% of their capacity.
In a more serious situation, the reservoirs of Campilhas and
Monte da Rocha, both in the Sado river basin, with, respectively, 12% and 10%
of their capacity, and Bravura, in the Western Algarve, with 12% of the total
volume stored.
According to the APA, on Monday and compared to the previous
bulletin (January 9), there was an increase in the volume stored in 10 river
basins and a decrease in five.
On Monday, with less water availability were the Barlavento
(12.3%), Mira (36.10%), Arade (41.8%), Alentejo (53.2%), Sado (54. 2%),
Sotavento (57.8%) and Mondego (69.1%).
The Tagus (94%), Douro (93.2%), Lima (89.5%), Vouga (89.4%),
Guadiana 887.3%), Cávado (79.3%), and Oeste basins (77.7%) were the ones with
the highest levels.
Storages in the first half of January by river basin were
higher than the storage averages for the month of January (1990/91 to 2021/22),
except for the Mondego, Sado, Mira, Arade, Ribeiras do Barlavento, and Ribeiras
basins from Sotavento.
Each hydrographic basin can correspond to more than one
reservoir.
How can it be that three are still below 20%?

Just a thought: some of these reservoirs are nearing 100%; if rain keeps on pouring, couldn´t we “give” the extra that won´t fit those dams soon, anyway – to those dams faring poorly? During summer some places across Pt had to receive h2o from other places. This would give those Dams (areas) more to work with while preventing the fuller ones from overflowing. Better water distribution throughout Pt, people would be better taken care of in terms of h2o availability?
