The results of 90 of the approx. 170 existing measuring points were evaluated for the relevant summer half-year (1 May to 31 October). The means for phosphate, ammonium and the oxygen-saturation index are presented here, as are the worst values for minimum oxygen levels and the titre for Escherichia coli that occurred during the summer half-year.

The results of 57 of the approx. 170 existing measuring points were evaluated for the relevant summer half-year (1 May to 31 October). The maximum and minimum levels that occurred during these six months are presented here, as are the mean contents of chlorophyll-a for different periods of time, the visibility depth and lindane concentrations in the sediment.
