Lake Tekapo is the second-biggest of three generally parallel lakes running north–south along the northern edge of the Mackenzie Basin in the South Island of New Zealand (the others are Lake Pukaki and Lake Ohau). It covers a region of 83 square kilometers (32 sq mi), and is at a height of 700 meters (2,300 ft) above ocean level. The lake is encouraged at its northern end by the plaited Godley River, which has its source in the Southern Alps toward the north. The lake is a prevalent traveler goal, and a few resort inns are situated at the township of Lake Tekapo at the lake's southern end. The Lake Tekapo Regional Park, managed by Environment Canterbury, is situated on the southern shore of the lake. A cosmic observatory is situated at Mount John, which is toward the north of the town, and south of the little Lake Alexandrina.
