I run Perl scripts that suck in internet information about river
gauges and generate APRS formatted packets, then inject them into
Firenet.us for everybody to see.  Something like 4000 to 5000 of
them at last count.  I could help you with the format if you want to
duplicate mine.

As far as the river gauge hardware itself, I remember there was
someone marketing such a thing, that would put out APRS packets
directly I think.  I don't remember the company name but perhaps
someone else here does.  I could do a grep through my mail folders
from a few years back and perhaps find it if necessary.
