Historically there was a USGS gauge at Index (stn. 12134000, 1910-1948, 146 sq. mi.). The virtual gauge for this run provides approximate flow based on the relative area of the basin and the Skykomish at Goldbar gauge downstream (the river is optimal around 10,000 cfs on this gauge). The relationship used for the virtual gauge is of course dependent on snow level. When the freezing level is low the river will be flowing a bit lower than the value given and during peak snowmelt the river may be flowing higher. The Goldbar gauge is also available through the NOAA hotline 206-526-8530.
