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 ideal druing spring snow melt at between 8,000 and 10,000 on this gauge). While you can run this river much lower on the Goldbar gauge, it's a lot more enjoyable when the rapids are filled in and the pin potential goes down. 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 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).
