How full are the dams? A large proportion of Auckland’s drinking water comes from 10 dams in Auckland’s Hūnua and Waitākere ranges. In February 2021, the 10th and smallest dam, Hays Creek Dam, was recently reconnected to the network boosting Auckland’s capacity initially by six million litres a day and by up to 12 million litres a day by April 2022. Recent rain has helped replenish our dams following the drought of 2019/2020.
