  abstract = {{T}he processes that form intraglacial lakes are poorly understood because of the difficulty in detecting and assessing such hidden lakes. {E}xtensive geophysical surveys were performed between 2007 and 2010 in order to reassess the risk of an outburst flood from {G}lacier de {T}ete {R}ousse, {F}rench {A}lps, where outburst flooding from an intraglacial lake caused 175 fatalities in 1892. {O}ur geophysical survey combined ground-penetrating radar measurements and nuclear magnetic resonance imaging. {W}e found a subglacial water-filled reservoir with a volume of 55 000 m(3). {A}rtesian outpourings occurred when the subglacial cavity was reached by two borehole drillings, indicating that the hydrostatic water pressure exceeded the ice pressure at the bottom of the cavity. {O}n the basis of these geophysical and glaciological findings, we warned the public authorities in {J}uly 2010 of the risk facing the 3000 inhabitants downstream of the glacier. {T}he subglacial reservoir was drained artificially. {T}his example demonstrates how geophysical surveys can be used to detect this type of hazard when it is suspected, in particular when no hydraulic outlet from the snout exists. {N}umerous ice temperature measurements have shown that the tongue of this glacier is cold-based. {T}his thermal regime could explain the accumulation of water in this glacier.},
