This is Lake Taupo, courtesy of the Internet. Next weekend we will travel up there, and have a night away, for my birthday, and catch up with daughters from North and South.
Lake Taupo is in the Caldera of the Taupo Volcano, is the largest lake by surface area in New Zealand, 238 square miles or 616 sq, kilometres,
For the Geologists, it is oligotrophic, with these rivers flowing into it, Waitahanui, Tongariro and Tauranga Taupo. The main outflow is the Waikato River at the northern end, Lake Taupo has a catchment area of 1,346 sq. miles or 3,487 sq. km.It is some 29 miles long ( 46km) and 21 miles wide (33km) the maximum depth is 610 ft, or 186 metres.
The average July water temperature is 12Celsius, today it was 11.7C, in summer maybe 19 Celsius, If you fall into the 10 Celsius lake water in winter , the sad fact is you will not usually survive over 2 hours, Hypothermia is the biggest threat.
So I will not be swimming or even out on a boat or float plane.
