Hydrological Atlas of Switzerland – Plate 7.2
The depiction of the average concentrations of selected chemical parameters in rivers and lakes is based on results of water quality studies carried out by the cantonal and federal institutions in the years 1987 to 1989. For the map-making, parameters were selected which serve to indicate the impact of civilization on a river: orthophosphate, ammonium, nitrate and dissolved organic carbon.
