Lake Tekapo is a village located at the southern end of the lake of the same name in the inland South Island of New Zealand. The lake is a popular tourist destination, and several resort hotels are located at the township. The lake's outflow into the Tekapo River is close to the village. The lake is at the upper end of the Waitaki hydroelectric scheme, and as such, several dams and artificial canals are found near its outflow, linking it with Lake Pukaki.Selected for its very clear atmosphere, large number of clear sky nights, and lack of light pollution, Mount John University Observatory is located on a small hill to the north of the town, and south of the small Lake Alexandrina. Originally set up by the University of Pennsylvania (looking for a southern hemisphere location), it is now operated by the University of Canterbury. From 1969 to 1982, the United States Air Force had a satellite tracking station adjacent to the observatory.The NZ Army has a large training range located at Tekapo. It is used for general military exercises and for pre-deployment training of forces being sent to Afghanistan.
