Informe sobre indicadores de sequía y escasez (septiembre 2022)

Report on drought and scarcity indicators in the Tagus basin (September 2022)

You can now consult the latest report on drought and shortage indicators in the Tagus basin for September 2022, in which two areas enter a situation of prolonged drought and one area is on alert due to shortages.
Two areas have entered a situation of prolonged drought, Cabecera and Árrago. The rest of the basin is in a normal situation.
The contributions in the Headquarters have been less than 50% of the average. That the headwaters of the Tagus enter a situation of prolonged drought should be one more element to take into account in the exploitation rules of the Entrepeñas and Buendía reservoirs.
Water inflows to the Árrago reservoirs have been practically nil (less than 1 hm³) during the months of July and August.
In a situation of prolonged drought, no body of water affected by the Tagus Headwaters can see its flow reduced below the established legal limits.
In prolonged drought, flows in the Árrago River could be reduced by 0.03 m³/s. But complying with the minimum ecological flow should not be a problem since it would represent only 2.4% of the current dammed volume.
The Bajo Tajo area has entered an alert situation (severe shortage) and, for its part, the Riegos del Alagón UTE continues in the constant pre-alert situation (moderate shortage) of recent months.
The alert situation of the Bajo Tajo is compatible with the satisfaction of urban, agricultural and industrial demands, as well as with the flows provided for by the Albufeira Convention.
