Gauge Description:

The gauge is very convenient for this run, being the Davis gauge just upstream of Blackwater Falls. Generally, the Upper Blackwater is run most between 250 cfs and 325 cfs. However, the Upper B is enjoyable on down below 200 cfs. I like to see 150 cfs or higher before I'll drive out (I have done it as low as 80 cfs, very scrapy). Between 150-250 cfs, the river is not pushy and is channelized enough that there is not a lot of scraping. This is a great level to see the run at for your first time. As the water progresses over 300 cfs, there is more padding but also a lot of power. Nasty holes begin to develop and the distance between rapids shrinks. Once it reaches 400, most paddlers will want to head elsewhere. My personal cutoff is at 500 cfs. Of course, there are guys that run it at higher levels than I do--and I wish them the best of luck.
