Visual. Look for flows of about 600 cfs. There was a USGS gauge on this river (stn. 12054500, 1951-1979, 51.3 sq. mi.) but it is no longer active. If you take a look at the staff gauge (river left just below Watson Creek), Korb notes that 1.2' is about the minimum for this run. Flows around 1200 cfs on the South Fork Skokomish are about right for good intermediate levels on this run.
Reports give the public a chance to report on river conditions throughout the country as well as log the history of a river.
