meaning

The Zêzere is the second largest river in Portugal after the Mondego . With its three dams and reservoirs Cabril , Bouçã and Castelo do Bode, it is important for both electricity and water supply. In particular, the Castelo do Bode dam, completed in 1951 , whose reservoir extends upwards from its dam at Martinchel for several kilometers, supplies part of the electricity and water requirements of the capital Lisbon.

The Zêzere offers numerous water sports, especially on its lakes. In addition, the wooded riverside areas are considered recreational areas. The Zêzere is one of the most popular Portuguese rivers for canoeing .

After the water quality of the Zêzere was found to be below average by the Portuguese national water institute INAG ( Instituto Nacional da Água ) until the mid-2000s , a large number of measures to increase the quality have been carried out since then. The moderately severe adverse effects from heavy metals originate from wastewater from ore mines in the upper reaches of the river. From around Dornelas do Zêzere , the loads in the water of the Zêzere decrease noticeably.

The river is the eponymous reference point for a large number of places and regional organizations, including the district town of Ferreira do Zêzere .
