How close to realtime is the data you can access?

Athttp://montana-riverboats.com, if you hover the mouse over
"Stream Flows" at screen middle bottom, you get (most of) Montana's
most important flows in a popup panel, updated nightly, using cron
and a little php/curl screen-scraping...querying the gov flows site at
3:00am
in the morning mountain time.

It takes about 90 seconds to complete, so it can't be done from a
mouse click.
But they only update the data once a day anyway. *So once a day
updates are as good as it gets.

Thanx. That adds another source. Two questions: I am assuming the data
are in Cfs, so would that figure represent an average for the previous
24 hours, or is it an instantaneous (point in time measure)? Do you
know where the data comes from original source)? What's with that
figure for the Madison below Hebgen Lake? Is it actually 1.something
cubic feet per second? That's worse than a household well.
