Annual exports of total phosphorus, soluble reactive phosphorus, and total nitrogen are presented for the period 1965–1974, for five rivers draining into the Bay of Quinte, Lake Ontario. The export values are typical for the physiography and land use though the results indicate that soluble reactive phosphorus exports for the four largest rivers have been declining. Also the variation in export of total phosphorus and total nitrogen is highly correlated with variation in annual runoff. This is noted as being a factor deserving more attention in future efforts to classify nutrient export values in relation to land use and geology.
