Lake Ellery is a glacially-formed lake in South Westland on the West Coast of New Zealand's South Island. It has a steep and entirely forested catchment, with a diverse flora and fauna, and is accessible only by foot or boat. Sediments laid down by its tributaries have preserved a 2,000-year record of ruptures of the nearby Alpine fault.
