The ideal streamflow range for this run is between 600 and 1,200 cubic feet per second (cfs), as anything below 500 cfs makes the run too technical and anything above 1,500 cfs is too dangerous. The run is rated as class IV-V, due to its steep gradient, tight turns, and numerous obstacles. The segment mileage of this run is approximately 8 miles.
The specific rapids and obstacles that paddlers will encounter on this run include Clavey Falls, which is a steep 20-foot drop that requires precise boat control to navigate, and Ramshorn Falls, which is a narrow chute with a difficult entry. Paddlers must also be aware of numerous boulder gardens and strainers throughout the run.
The Confluence With North Fork And Middle Fork Stanislaus To Clark Flat run is within the jurisdiction of the Stanislaus National Forest, and therefore, specific regulations apply. The Forest Service requires all paddlers to have a personal flotation device and a helmet. Paddlers must also obtain a permit before accessing the river. Additionally, the Forest Service may close the river during periods of high water or fire danger.
