Lower Boulder Canyon


As a Boulder local, I have a love hate relationship with Boulder creek.  It's Boulder's main artery and so much fun at elusive high flows, but so rocky and poor quality at low flows.  Why people insist on dropping everything to run this stretch of "almost" whitewater at 200 cfs is beyond me, especially since there are almost always better options with just a little extra driving.  Maybe it's the hords of slightly intoxicated college girls in bikinis tubing through the sticky whitewater park in town.  For me, the run gets good when the tubing ban goes into effect for the creek (about 500 cfs).

Suggested river levels for paddling this section of the Boulder Creek are between a bare minimum of 250cfs and a high of 1,300cfs. River conditions sourced from USGS 06730500, the Boulder Creek At Mouth Remember only watercraft are permitted at Lower Boulder Canyon.
