The CC Stilly gauge has been permanently removed as of June 2011 according to the web page on the DOE.
Fortunately, there is another way to get an estimate of the flow of the water in the creek if you are willing to do a little math. This method assumes that the DOE gauge on the SF Stilly https://fortress.wa.gov/ecy/wrx/wrx/flows/station.asp?sta=05A105&historical=true - (link) and the USGS gauge have station rating tables that are accurate. A visual check yesterday at one flow indicates that the method described below is certainly in the ball park and a much better estimate of flow than just looking at the SF Stilly gauge alone.
The DOE gauge is located at Jordan Road, just downstream of where CC Stilly joins the SF Stilly. The USGS gauge is near Mountain Loop Highway, just a little above the Falls. There is no significant tributary of the SF Stilly between theses gauges except CC Stilly and the gauges are very close together. So, get the flow from the downstream gauge and subtract the upstream gauge and presto, you have a good guess at the flow in CC Stilly. I should note that on the DOE site, the DOE gauge, like virtually all of the DOE gauges only updates every 3 hours with a one hour delay. You can go to the NWRFC and get a more up to date stage level of the DOE gauge if you are interested and know how to do the stage/cfs conversion yourself for that gauge.
So, yesterday, for example, at 11:00 AM, when the SF Stilly gauge was @ 5.97' (1527 cfs), the DOE gauge was reading 1960 cfs implying 430 cfs in CC Stilly (and a visual check confirmed this reading). Normally 5.97' in the SF Stilly would be associated with much higher flows than this.

Hey, nice nice work!
I've found that winter rains put a lot more water in Canyon Creek relative to the Robe.
On rain, Canyon Creek will be higher relative to the robe. But, on snow melt, especially later season snowmelt, Canyon Creek will have relatively less water.
IE: 5.8 Robe in the winter is a lot more water in CC than 5.8 Robe in the Summer snowmelt season.
