River Description

The Slab Creek reach begins with several class IV+ rapids that are within sight of the put-in. The river continues in a very continuous nature for the next four miles. Many of the rapids are fairly long and require good class IV skills The most significant rapid on the run occurs shortly below the Mosquito Road Bridge at river mile 3.6. The gradient eases at this point and the run becomes class II/III in nature. There also is more vegetation, primarily Alders, in the river channel after this point. Rock Creek enters on river right at river mile 5.5. The Rock Creek Power House could provide a potential take-out or put-in if paddlers were interested in running the last two miles of the run down to White Rock Power House. This section is also class II/III with one rapid that is potentially class III+.
