Just found this today, it might be useful to add this to the quiver of ways to get flow information.


m.waterdata.usgs.gov

It's still in Beta and I haven't actually used it on my phone but it has to be a bit better that the regular waterdata site for navigating on the phone.

Checked to see if NWFRC had one but it doesn't appear that there is.

If PPeeps have used this in the past please chime in, I'm curious about it's functionality and limitations.
