In spite of the heavy storms, water authorities in the north of Bohemia say they are facing some of the most serious water shortages in the last 50 years. The reservoir at Chomutov, the fifth biggest in the country, is at the lowest level since it was constructed at the end of the 1960’s and tankers with drinking water are being prepared in the case the situation becomes worse. Bans on pumping water from streams and rivers are already in place at numerous localities across the region. The main problem stems from low snowfall in the winter which helps to fill up reservoirs and ground water reserves. Temporary storms will not resolve the problem, authorities say.
