While Maori had long known of its existence, the first European to reach the lake is thought to have been Nathaniel Chalmers in 1853. Accompanied by Māoris, he walked from Tuturau (Southland) to the lake via the Kawarau River, later returning by a raft floating down the Clutha.
Around 1859, other explorers who were now mapping the area also found a ruined Māori village (destroyed in a tribal raid in 1836) in the Makarora Valley.
Around 1861, several new sheep stations had been established in around the south end of the lake, and in 1862, the lake itself was surveyed in a whaleboat.The early European name was Lake Pembroke.
This is the top of the lake just before the road takes you over to the west coast of the island.
