Likely low to moderate. (Best flows uncertain! Please help your fellow boaters by adding a comment about best flows, and class/difficulty at various flows!)
Scratch rapid presents a technical navigation challenge with multiple boulder-strewn channels that require precise boat placement and quick maneuvering. Paddlers must carefully read the water and choose their line, avoiding potential pinning hazards among the scattered rocks and potential undercut formations. While not particularly steep or high-gradient, the rapid demands constant attention and skilled boat control to successfully thread through its complex rocky terrain.
