Upper South Boulder Creek
USB is a short class V wilderness run near Boulder infamous for its ability to destroy boaters. For some local hair boaters, this is their backyard training run. For others, it's a run they contemplate stepping up to from the comfort of their living room in the off season, only to be forgotten about while spending the spring running Clear Creek. For most boaters, it's one they gawk at in the guide book on their way to run Brown's Canyon.
Suggested river levels for paddling this section of the South Boulder Creek are between a bare minimum of 250cfs and a high of 800cfs.
River conditions sourced from USGS 06730200, the Boulder Cr At North 75th St Nr Boulder
