60-150 ppm (mg/l) is desired for best fish growth (healthy ecosystem). 60% of surface water in KS is 100-300.
This is also a pH buffer to subdue wild swings ..
To better answer your question, yes, it has a lot to do with location, water source and what substrate that water flows through/over before it gets to pond.
