The Nisramont dam complex was built in 1958. The intention was actually to create a much larger lake with a dam at the Celtic site of Le Cheslé. Not coincidentally there, because as we will notice during the next stage on the Escapardenne Eislek Trail, the Ourthe is strongly incised here and it is therefore technically ideal to dam even further downstream from that deep incision. The storage capacity is expected to be up to 250 million m³. The current Nisramont dam was therefore built as a temporary project, but more than 50 years later it is still standing.
