[aprssig] River Gauging APRS setup

Gentlemen,

I find this to be a very interesting topic.   You see, next spring I might get a phone call from the National Weather Service and then I take the key and drive to the river gauge, open the padlock, lower the "sensor" and read the value, then restore everything and drive to the next gauge and then the next.   This may take 45 minutes.   Then I email NWS my report---or I could radio it to them but the email is preferred because it provides a record that is easily handled.  Now, since there is that padlock to be considered I hope that any plans would include provisions for security---especially if I am paying for this!

But I must warn you that a suggestion by me that realtime water/flood photos be "radioed" by ham radio to the hydrologist was met with absolutely no enthusiasm.  Acceptance of new ideas, even though they have merit, can be difficult!

    I just searched my email archives and this is what I found. Link doesn't work.  I do remember this thing though, it was in a PVC pipe and shot an ultrasonic transducer down the pipe to measure the distance to the water surface.  I think the guy that made it was in Florida.... but not sure.

      Somewhere I've seen plans for a simple river gauge setup with APRS, seems to
      me it was a micro power transmitter, the thing ran on several 6v lantern
      batteries, PVC conduit into the river for the sensing portion and an antenna
      on top of the PVC.  I can't find it, does anyone remember this and have the
      link or info on this?

      Thanks,
