Hi,
Thanks to all who responded. I now have some good leads. Here's a
summary of the replies so far.

I imagine you'll receive more useful responses, but I know these exist
for *fuel* applications: generator fuel tanks and so on.
Good luck - sounds like a fun project!
I am only familiar with the systems that are utilized on most
'real-time' stream gaging stations, such as those run by the USGS. As
you might know, these stations while straight forward to install are
relatively capital intensive (~$10K for a USGS-type station). I'm
assuming you don't need something of this caliber - if you do I would
talk to your local USGS office as they can suggest the equipment
you'll need to transmit and then receive real-time data.
Alternatively, I would check out the Onset Corporation to see what
they offer. I'd be curious to know what you find.
We use a weather station by Onset Computer (onsetcomp.com). I know they
make water level recorders.

The loggers for their weather stations have the ability to be accessed
online. So, perhaps the same for their water level recorders.
Off the top of my head, I know that Onset Computer Corporation
(www.onsetcomp.com) has water level recorders and other units that transmit
weather data wirelessly. But I do not know if they have one that will do it
for water level alone. I would try calling them if they don't appear to have
anything on their website. Good luck.
we use telemetric ATT modes and they work quite well - you can buy them
at Campbell scientific.

please consider subscribing to hydrolog-l an email list for hydrology
that I have set up. This type of question is right at the centroid of
expertise for the user-base for that list.

I've had moderate success running ichart software with Nexsense data
loggers (http://www.nexsens.com/) connected to YSI6920 gages. The YSI's
collected data. The Nexsense logger downloaded the data through a cable to
its location on a pole on shore every 10 minutes. Every 30 minutes, the
logger would send the data to a base station via spread spectrum radio.
The base station was connected to a computer with internet access, so the
data were transmitted to a web site every 30 minutes. Things may have
gotten better, but the software was very temperamental and not easy to
work with a couple years ago.
Focus your search on telemetry systems since you'll be able to use a wide
variety of water-level recorders.
I saw your post on Ecolog and thought I would send you some information for
Solinst water level gages. I have used the Solisnst Leveloggers to monitor
water level in creeks and was happy with performance. I had them setup to log
data and then downloaded the data monthly. The probes had great battery life
and a lot of memory.
I don't have experience with accessing the data remotely but their website (see link below) has a remote telemetry option.
