Shown here is the 150 acre Lake Puki Puki, near Himatangi, which dried up during the drought of 1969 - 1970, for the first time in living memory. The lake was one of several resulting from the formation of sand dunes along the coast which prevented inland water run-off escaping to the sea. Its average depth was usually 4-7 feet and it was fed by a drain known as the Puki Inlet and from water pumped from Mr P R Barber's property during wet weather. The lake now forms part of the Pukepuke Conservative Area and is an important wetland habitat.
