The hydrological study of the lake Grand-Lieu, proves (among other results) the essential role played by the hydrometeorological data, mesured at least in some discarded points in study area, both for the modelling of the basin's outflows as well as for the lake water balance. * The simulation of the lake inflows was validated by two different ways: a conceptual model (upstreaming model) and a descriptive synthetic model (downstreaming model). * In the present paper we are giving only the modelling results of the basin's outflows and the lake water balance simulations. This step is an unavoidable one before any objective choice of an efficient water-Iake management policy.
