About the data

Austria brings two worlds together: the provincial hydrographic services of Lower Austria, Tyrol, Carinthia, Upper Austria, Salzburg and Vorarlberg measure rivers and lakes every fifteen minutes, while AGES samples the bathing lakes every two weeks during the season. Wörthersee, Attersee, Lake Neusiedl and Carinthia's lidos sit side by side, each with its measurement time stated honestly.
