Twenty—two water quality parameters were determined for the streamflow from complex but typical upland—peatland watersheds over a period of 5 yr. Five watersheds with oligotrophic peatlands and one with a minerotrophic peatland were studied. Concentrations of organically derived nutrients are highest in the streamflow from watersheds containing oligotrophic peatlands; while concentrations of nutrients derived from solution of aquifer minerals are higher in streamflow from the watershed containing a minerotrophic peatland. However, flow—weighted concentrations of organically derived nutrients are similar for both watersheds. Annual nutrient yields (kilogram/hectare per year) calculated for two of the tight upland—oligotrophic peatland watersheds are generally low and are quite similar to values for other forested areas in North America which do not contain peatlands.
