  <dc:description>Sources and transport for phosphorous and nitrogen to the Tualatin River, Oregon, were characterized for summer (May through October) low-flow conditions during 1991, 1992, and 1993. Mass balances for water and chemical constituents, which were generated for the main-stem river, provide important context for nutrient-reduction efforts in the basin.</dc:description>
