This.s.udy aimed to evaluate the external and internal fluxes.of nutrients.of an urban eutrophic res.rvoir （lbirit6 res.rvoir, s.-Brazil）. External loads.were es.imated in the tributaries.（Pintados.and Ibirit6 creeks. through nutrient concentrations.and dis.harge meas.rements. Us.ng Fick＇s.law, internal loads.were es.imated in the res.rvoir from fluxes.acros. s.diment-water interface from nutrient concentration gradients.between the pore water and the water. The Ibirit6 creek （urban s.wage recipient） contributes.with 72%-47% of ammonium （NH4^＋） and 100%-8% of s.P （s.luble reactive phos.horus. of the total quantity entering the res.rvoir, whereas.the Pintados.creek （oil refinery effluent recipient） contributions.are 20%-19% and 44%-100%, res.ectively. Des.ite the high external loads.（130 and 2.2 ton-yr^-1 of NH4＋ and s.P, res.ectively）, internal loads.（average flux of 120 and 2 mg·cm^-2yr^-1, res.ectively） corres.ond to 25% of the total external loads.which may s.s.ain a high productivity in the res.rvoir for a long time even if the external loads.are controlled. The s.ocks.of ammonium and s.P of the inters.itial water （100 cm of s.diment） would be releas.d to the water in s.x years.and five months. res.ectively, The releas. time would be extremely larger （〉 3,000 years. cons.dering the s.ocks.of total N and bioavailable P.
