Gauge Description:

The ideal level is from 1000cfs down to 700cfs. Under 700 the river gets small but is still tons of fun, and over a 1000 the undercuts are better padded out but you are looking at really pushey water. Most mortals consider 1500 the max but there is always a few out there that have made runs over 2500 cfs. The gauge is now reading low. Most people tend to agree that you have to add 150 cfs to the gauge now.

420-700: Slow but fun.
700-900: Fun level, Feels more like a creek.
900-1500: Gettin scrary! Pushy!
1500-?: You must be crazy!(or really, really good.)
