Perry River - The Upper Perry is a popular option during the spring when other creeks are too high. There are two put in options, one immediately below the Upper Canyon and one above the Upper Canyon. At lower levels (>80cms) the Upper Canyon adds two fun IV/IV+ rapids to the run. At higher flows (<80cms) the canyon quickly becomes class V and is most often portaged (on river left). Look out for Carls hole, an extremely trashy hole at the bottom of a long rapid mid run. It features an undercut rock island immediately downstream that often collects wood just to add to the hazard.. If the Upper Perry is too low be sure to check out the Lower Perry Canyon!
