You are right Gary,

I should have prefaced my notes with the application to Australian
conditions. The only trip to PNG was to Kikori and we found one of the
rainbows that Gerry Allen didn't find until a few months later but of
course we weren't allowed to bring any back. :-(

The lower reaches especially had fantastic limestone formations.

<<Dr. B - are you talking about Oz or NG when you say "that I have been
able to
test have been rather soft ( ? low in Ca and Mg) except in Limestone
country."?
Since you've written about both places now it may be potentially confusing.
>From my understanding from what you and others have written that a lot of
the
waters in Oz are soft (10-90 ppm) in general hardness, and dissolved solids
in
general (your use of a conductivity meter and fairly low #'s reported
suggests
that). It does seem though that some of the NG fish do hail from areas
where
the water is much harder. I think that lacustris was a good example of
that, if
I remember correctly Jerry/Heiko talking about swimming next to the
limestone
cliffs.>>
