Focus is on Sau reservoir, where water supplies have plunged to their lowest level since 1990
Officials in Catalonia have launched what is being described as an extraordinary operation to clear as many as 1.5 tonnes of fish a day, including many invasive species, from a rapidly dwindling reservoir in the hopes of salvaging drinking water as drought continues to grip the region.
The operation is focused on the Sau reservoir, a sprawling body of water flanked by mountains and tree-covered hills about 60 miles north of Barcelona, where water supplies have plunged to their lowest level since 1990.
