Is there a website that water meters on rivers report to? I am planning a white water river trip and I am worried the river will be dry. I know there are meters on the river but accessing them or finding a website with the current levels is a nightmare for one river to the next. I live in Arizona so ideally the site would at least have my rivers but I often head to Utah for the Colorado, the San Juan, and the Green rivers.

This is an easy to read table for GA, but I can't figure out how to navigate to other states on their site: http://www.srh.noaa.gov/ffc/html/rva.php
