Lake Bled is an alpine pearl in the north-western part of Slovenia. In this century eutrophication has progressed rapidly, endangering this previously beautiful oligotrophic lake and the tourist economy of Lake Bled region.

This paper presents basic facts about the lake and modelling approaches undertaken to define the proper restoration measures. Several models were used, beginning with the simplest Vollenweider model, continuing with Imboden's two box steady-state model, progressing to a dynamic three box model, then modelling of circulation by a 2D and later by a 3D hydrodynamic (HD) model.
