Gauge Description:

CO Water Talk: 303-831-7135
Division 4, Station 6 (4*6*). Gunnison Below East Portal

The Black Canyon can be run as low as 400; however, a good level is around 700 and above. The river is still high quality at low flows, except for the 18 foot waterfall which requires a creative portage (rappelling, jumping, or scrableing) at flows less than 550 or so.
The season for this run is whenever it is free of ice, since the Crystal dam keeps the flow running at a fairly constant rate. The best time to hit the Black Canyon is usually late summer when most of the snow-melt rivers are spent for the year.
