Numbers


The Numbers is a classic stretch of class IV whitewater on the Arkansas River upstream of Buena Vista.  When the water is high and the sun is out, this is about as good as class IV boating gets in Colorado.  At low and medium flows expect to see a lot of kayakers and rafters playing their way down the river.  At higher flows, you may have the run all to yourself, even on a weekend.

Suggested river levels for paddling this section of the Arkansas River are between a bare minimum of 200cfs and a high of 5,000cfs. River conditions sourced from USGS 07087050, the Arkansas River Below Granite Remember only watercraft are permitted at Numbers.
