Background
It was first conceived in the 1950s to help replace nature groundwater resources for the town of Esch-sur-Sûre. Using an André Coyne design, the dam was constructed between 1956 and 1957 and the power station was commissioned in 1963.[1] The reservoir has been drained twice during the dam's life; once in 1969 to install a new fixed water intake and again in 1991 to install and adjustable-arm intake which mitigate issues with algae growth in the reservoir.[2]
Dam
The Esch-sur-Sûre is an arch dam with a height of 50 m (160 ft) and length of 170 m (560 ft). It is 1.5 m (4.9 ft) wide at its crest and 4.5 m (15 ft) wide at its base. The dam sits at the head of a 428 km2 (165 sq mi) catchment area and creates the Upper Sûre Lake which has a total volume of 59,000,000 m3 (48,000 acre⋅ft). The lake has a surface area of 3.5 km2 (1.4 sq mi) and is 19 km (12 mi) long. It is 43 m (141 ft) at it deepest point and the normal elevation is 322 m (1,056 ft).[3]
Power station
The power station at the base of the dam contains two 5.5
Spillway plans
The dam also provides for flood control but has no spillway. Currently, two bottom outlets with a 450 m3/s (16,000 cu ft/s) discharge capacity pass floods through the reservoir. Floods in the 1990s highlighted the need for a spillway at the dam. A design for a chute spillway on the left abutment of the dam have been drafted but not implemented.[3]
