The maximum water depth is 48 metres (157 ft) and at 100% capacity the dam wall holds back 425,510 megalitres (15,027 × 10 ^ 6 cu ft) of water at 329.6 metres (1,081 ft) AHD. The surface area of Lake Keepit is 4,370 hectares (10,800 acres) and the catchment area is 5,700 square kilometres (2,200 sq mi).
WaterNSW also owns and operates the largest surface and groundwater monitoring network in the southern hemisphere. [ 2 ] WaterNSW was established on the 1 January 2015, under the Water NSW Act 2014 , merging the State Water Corporation (which managed the states rivers and dams other than Sydney) and Sydney Catchment Authority which managed ...
[8]: 15–17 The Scheme was a significant feat of engineering at the time of construction. In June 1885 Sydney was in the grip of a severe drought and the Upper Nepean Scheme was incomplete. The Government accepted an offer from Hudson Brothers to bridge the gaps and deliver 14 megalitres; 3.6 million US gallons (3 × 10 ^ 6 imp gal) of water ...
The maximum water depth is 79 m (259 ft) and at 100% capacity the dam wall holds back 1,220,000 ML (43,000 × 10 ^ 6 cu ft) of water at 379 m (1,243 ft) AHD. The surface area of Lake Wyangala is 5,390 ha (13,300 acres) and the catchment area is 8,300 km 2 (3,200 sq mi).
Testing conducted by Sydney Water in June 2024 found that levels of PFAS in the Cascade Dams were greater than 10ppt. [5] Levels of PFOS and PFHxS in the "Katoomba" Cascade dam were measured at 16.4 and 14.2ppt respectively, while the "Blackheath" dam contained 15.5 and 13.6ppt respectively. [ 5 ]
The maximum water depth is 56 metres (184 ft) and at 100% capacity the dam wall holds back 283,000 megalitres (10,000 × 10 ^ 6 cu ft) of water at 186 metres (610 ft) AHD. The surface area of Lake Saint Clair is 1,540 hectares (3,800 acres) and the catchment area is 233 square kilometres (90 sq mi).
The New South Wales State Government tried to reduce this risk by implementing water restrictions [21] and commissioned the construction of a desalination plant, at Kurnell. Heavy rains between June 2007 and February 2008 restored the dam level to around 67%. Despite this, Level 3 water restrictions remained in place until 21 June 2009. [22]
Greatest depth of water: 46 metres (150 ft). Full supply level: 290 metres (950 ft) AHD. Area of lake: 851 hectares (2,104 acres). Capacity: 97.19 gigalitres; 25.67 billion US gallons (97,190 ML). The water from Cataract Dam is discharged as required into the Cataract River downstream to Broughton's Pass.
