Here's the link: http://www.nwrfc.noaa.gov/river/river.cgi?zoom?2?1.1.1.1.0_1.1.1.1_1?zoom?119,213?197,411
with the zoom set for the north end S rivers. You can reset the zoom for another location if you like. I think it is the same data as the other site but provides a forecast, which the other site does not. I also like the option to get a quick gauge reading without the charts by just moving the cursor over the site of interest.
