The springs are high in sodium bicarbonate, hence yes, it will be quite
high. One could easily get a minimum estimate by dumping sod. bicarb into a
cup of water, as you add more the pH will rise to 8.2, but as more is added it
will fall back to 8.0. If you took a kH reading when the pH first drops back
to 8.0 it will at least provide a minimum value. The springs are usually
around pH 8.

Mind you, I never had these problems in Melbourne water with the wild fish
which is low in almost everything. But they were wild fish cf. those raised
in captivity at lower kH.
