L'establishment a barrage on Gileppe was required by wool the verviétois about 1857, in order to have forty thousands liters m3 of pure water necessary every day to textile industry of time. The industrialists did not want to be especially any more under the cut of Eupenois, whose factories also used water of Vesdre, but in first hand. They wished, moreover, that each company of the place lay out d' a virgin water and equalize purity. The stopping was put underwater May 1875 and inaugurated on July 28, 1878 in the presence of the king Léopold II. In the following Sixties and, the outdatedness of work started to be marked more. Moreover, increase in the industrial needs and also the fear of the drynesses added the weight of their arguments in favour a modernization and a heightening of the old dam. The decision was made; the adopted formula took account of the war risks on a similar work and also of the possibility; an earthquake in the area as well as factors d' saving in realization. The existing wall, raised beforehand by a concrete dam of 20m rise, would be included in a vast methodically packed riprap: this one would form a mass of 1,2 million m3 of sandy materials taken in the career very close to Borchenne. The facings would consist approximately sandstone hardcores posed with the hand and fixed to form a facing. The realization of this titanic work carried this manner capacity of the Lake of Gileppe to 26 million 430.000 m3, including 24 million capacity m3 usable.
