Take a look at the drops upstream from Rt. 89. If they look like there at a good level everything else should be.
For an online gauge, look at Six Mile Creek in Brooktondale. It should be running pretty good at least 200 cfs, but since the gauge is on a different stream 20 miles away, it should be viewed as an educated guess.
