Remnants of Waipori town have reappeared as the level of Lake Mahinerangi has dropped. Because of a new assessment of earthquake risk to the dam, the lake has been lowered by just over two metres. This has revealed lots of reminders of Waipori town and the gold-mining activities. Check out an Otago Daily Times article from September 2019.
The lake has been low on previous occasions. The photo below was taken in 2008.
