Abstract Temperature, discharge, and chemical parameters were studied in the upper reach of a Black Forest stream over a three-year period. Additionally, investigations of the upstream tributaries and of downstream sites were conducted at some occasions. While monthly and annual means of water temperature exhibited only little year-to-year variations, average annual discharge differed considerably. Total suspended organic matter was correlated to total supended solids and discharge, orthophosphate and ammonium to temperature. Phosphorus was the only nutrient with a strong seasonal dynamic. Cumulative surface runoff of the upstream tributaries was inversely correlated to total discharge at the gauging station. Concentrations of Ca2+ and Mg2+ and accordingly specific conductivity increase in the longitudinal course of the stream, due to tributaries originating in the adjacent shell limestone and red marl formations.
