Deer Park that's good water?

LOL..

Off topic but I saw your title and thought you were from a suburb of Melbourne, Australia with the same name. Deer Park.

I live where there are quite a few places called deer Park, too although Lost Lakes are by far the most numerous.
Seriously, Just take along your test kits or meters and see what the water is like. I have found springs and small streams on the west side of the Cascades when I lived in Seattle with a pH of 5.5 and TDS of 25 ppm and brought some home for Tetra breeding projects. You never now until you test it whether its close to what you hope to find.
