About the data

Germany is the densest network in BrrChecker: the bathing-water networks of Mecklenburg-Vorpommern, Brandenburg and Schleswig-Holstein cover the lakes with samples taken through the bathing season, while PEGELONLINE, Bavaria's hydrological service and North Rhine-Westphalia's LANUV report the rivers hourly. The coast and the North Sea islands come from PEGELONLINE gauges and buoys. Bathing-water samples are seasonal; river gauges measure all year.
