Advanced Hydrologic Prediction Service: Seattle: Sauk River near Sauk

The solid blue line shows recent flow levels, while the dotted red line shows the National Weather Service’s flow forecast for the Sauk River. If flows reach 30 kcfs (the number on the right side of the graph), SSIT’s flood watch begins. This would not mean the Sauk is flooding. The 30 kcfs level is simply when the Tribe starts monitoring the slough on the Reservation hourly for signs of erosion, in case the main river channel tries to divert into the slough. 

We also monitor flow levels on the Skagit and Stillaguamish Rivers (for driving access to and from the Reservation) on the following links:

 Skagit River near Concrete

 North Fork Stillaguamish River near Arlington

Stillaguamish River at Arlington
