   This is generally true, but not in the streams with which we're working.
TDS values, for example, vary by orders of magnitude between sampling
locations on the same stream, and not with any pattern. Also, specific
conductance/conductivity (Cond) varies within a stream.

   These variations may well be on different dates, but this first look needs
to ignore time. I'll eventually get to that aspect.

Thanks,
