Quality of Surface Waters (Chemistry) 2001

The quality classes of watercourse segments are presented here for the six-year period from 1991 to 2001, in accordance with the assessment of the water composition of running waters in the FRG (LAWA 1998). They are based on the minimum value of the random sampling data records and on the 10-percentile of the daily values measured over the course of one year. 02.01.1 OxygenMore information

The water temperatures of summertime-lowland waters are presented here for the six-year period from 1991 to 2001, according to our internal classification. They are based on the maximum value of the random sampling data records and on the 95-percentile of the daily values measured over the course of one year. 02.01.2 TemperatureMore information
