More than half of the 59 reservoirs monitored had, at the end of May, water availability greater than 80% of the total volume, while four had values lower than 40%, according to data from the National Water Resources Information System (SNIRH).

According to the data, of the 59 reservoirs monitored, 34 had water availability greater than 80 percent of the total volume at the end of May.

On the last day of May and compared with the last day of the previous month there was an increase in the volume stored in five river basins and a decrease in seven.
The Barlavento river basin had the lowest water availability at the end of May, with 31.7 percent, followed by Mira (49.3 percent).
