Dam and reservoir overview
Dam
Constructed between 1938 and 1941,[3][4][5][6] the concrete-faced rock-fill dam wall is 33 metres (108 ft) high and 244 metres (801 ft) long. When full, the resultant reservoir has a storage capacity of 20 gigalitres (16,000 acre⋅ft) and covers 208 hectares (510 acres), drawn from a catchment area of 190 square kilometres (73 sq mi). The 77-metre-long (253 ft)[7] controlled spillway has a discharge capacity of 1,295 cubic metres per second (45,700 cu ft/s). In 1949, the dam wall was raised and the secondary embankment was completed that is 7 metres (23 ft) high and 197 metres (646 ft) long, and includes both rock and earth-fill abutment sections.[1][8]
Reservoir
The reservoir is a popular picnic ground for fishing and is stocked with redfin perch, rainbow and brown trout, roach and cod. A picnic and BBQ area is located near the dam wall at the end of Lauriston Reservoir Road.[9]
