The Captain James Cook Memorial was built by the Commonwealth Government to commemorate the Bicentenary of Captain James Cook's first sighting of the east coast of Australia. The memorial includes a water jet located in the central basin and a skeleton globe sculpture at Regatta Point of Lake Burley GriffininCanberra, showing the paths of Cook's expeditions. On 25 April 1970, Queen Elizabeth II officially inaugurated the memorial.[1]
The water jet is driven by two 4-stage centrifugal pumps capable of pumping up to 250 litres per second against a head of 183 metres. The water velocity at the water nozzle is 260 km/h. While running both pumps simultaneously the main jet throws approximately six tons of water into the air at any instant, reaching a maximum height of 152 metres. Alternatively the jet can be run on a single pump reaching a lower height of 114 metres. During special occasions it can be illuminated, often with coloured lights.[2] The design of the jet is based on the Jet d'EauinGeneva, Switzerland as a result of high-level diplomatic negotiations.[3]
The water jet operates daily from 11 am to 2 pm.[3] In periods of high wind, the jet is automatically disabled as water landing on the nearby Commonwealth Avenue Bridge can be a hazard to traffic. The water jet must also be occasionally shut down when drought lowers the water level of the lake.[4]
