Building up by Paraguay and Brazil on Alto Parana River (APR), the reservoir covers in area 1440 km2 . Its impoundment of the right bank, Paraguayan side, flooded about 570km2 of vegetation, mainly of height and lower forest, crops and soil. Prior to the impoundment Itaipu Binacional conducted a large number of environmental studies, some of them in reference of the chemical effects of the biomass (BM) on water quality such us phosphorus supply and reduction of dissolved oxygen (DO) concentration, inter alia. In the latter, simulation experiment provides interesting data. This submersion/ incubation experiment on DO consumption were carried out with appropriate amounts of BM samples and APR water, in which DO were determined. Through the oxygen consumption decay curves and their kinetic analysis of the oxidation of the BM, they were found, fast processes with a high oxygen avidity, as well as others slower, with a relative low oxygen consumption, following both, e-ln2t/T kinetic; the former, of the order of days, are due to the oxidation of soft parts of the plants, like lives, shoots, petioles and twigs, while the latter, of the order of years are resultant to the hard parts, like trunks, logs, etc. The phosphorus supply by decaying vegetation at the right bank, was low in comparison to the amount carried by the APR. In addition, the low residence time of water in the reservoir allows fast DO input renovations.
