Always Obey the Rules!
Recently my wife and I had a few days break and stayed at a small town called Turangi,
at the south end of lake Taupo (a very popular tourist destination in the middle of the North Island of New Zealand).
Turangi has missed the tourist hoardes and is a lovely sleepy little town.
There is a small geothermal area near Turangi.
(complete with boiling mud!)
They've got a geothermally heated public swimming pool with an interesting sign, setting out the rules of use.
Although the water is sufficiently hot that it's far too much bother to attempt the active banned activities, but all the swimmers seemed to be wearing swimming togs.
They also have private pools where the water is the real thing, hot water full of minerals which comes out of the ground.
It is not a good idea to put your face in this water.
Now, I'm a fairly law abiding sort of bloke, so the next time I went for a swim
I did the right and proper thing!
This is at a small lake south of Lake Taupo called Rotopounamu which means "Green Lake".
It's a very beautiful place, and you can walk right around the lake which takes half a day to walk, doing it leisurely with lots of stops.
There are 3 streams which feed the lake, but no known outlet.
Probably there is an underground stream somewhere which drains the lake and keeps the water lovely and clean.
There could also be unknown underground streams feeding the lake.
The first few inches of water was warm enough, but it got rapidly colder as it got deeper!
I only stayed in a couple of minutes, and couldn't talk my wife into going in at all!
And the locals don't seem to be bothered by the occasional human visitor!
I don't know anything about the dragonfly,
but the ducks are a pair of Whio, or Blue Duck.
These are on the endangered list, mainly due to habitat loss caused by hydro
PS the ducks aren't on the lake, but a nearby river.
