Omarama is a small township (population 231 at 2006 census) at the junction of State Highways 8 and 83, near the southern end of the Mackenzie Basin, in the South Island of New Zealand. Omarama is part of the Waitaki District, which itself is within the Otago region. The Ahuriri River is a short distance to the north of the township.

Lake Ohau is a glacial lake in the Mackenzie Basin of New Zealand's South Island. It is fed by the Hopkins and Dobson rivers, which have their headwaters in the Southern Alps, and has its outflow in the Ohau River, which itself feeds into the Waitaki River hydroelectric project.

Ohau is the smallest of three roughly parallel lakes running north-south along the northern edge of the Mackenzie Basin (the others are Lake Pukaki and Lake Tekapo). It covers 60 km².

The Ohau ski field is located close to the southwestern shore of the lake.
