I've seen jet skis and motorboats there, but the two put ins are marginally suitable for a trailer launch, best for kayaks and canoes and other hand launch craft. Says Stan
Are jet ski's allowed on slab creek? Says Zack Heriman
Nearby there is a great 7-mile-long class IV-V whitewater part, the Slab Creek Dam to White Rock Powerhouse segment of American River - South Fork. This part of American River - South Fork is well suited for those proficient in raft
paddling. Near Slab Creek Reservoir is a great 20.5-mile-long section of whitewater on American River - South Fork, a category II-IV, this is the Route 193 to Folsom Lake segment.
