River in Flood - Mangahao Electric Power Scheme
This picture shows a flood which has gone through the workings causing major damage to uncompleted structures. The Mangahao Power Station provides hydroelectric power and is situated near the town of Shannon. It serves Wellington, Horowhenua, Taranaki, Hawkes Bay, and the Wairarapa. After being delayed by WWI, construction began in late 1919 and the station opened in November 1924.
