An excellent site. Graphs of your favorite stream showing real time water levels and/or flow. By keeping track of what levels at the gauge station mean for the water on your favorite stretch, you can determine whether the trip is worthwhile or whether it would be better to hit another stream.

cool site!

a quick glance over the bridge on the hoosic today tells me that current conditions are somewhere between "raging torrent" and "I knew that spillway was there for a reason".
