Anyone have beta on sapling levels compared to the newish USGS gauge on the SF Sky? Yes, I know it varies by season, but would be nice to start having some data on this. Seemed like anything below 5.4 on the old gauge means it was for sure too low (6" below the stick). Looks like the gauge was put in Oct 2016.

i always went roughly for 6' on the S fk guage.

Harms? Mike Harms was pretty dialed into the sfk gage for a bit there maybe he knows...

Let me clarify. I have a decent understanding of the old gauge, but the new gauge is a totally different datum. It's reading 18 ft or so now. Does anyone know if this is just a datum shift or a totally new gauge? I never recorded flow readings on the old gauge, just stick levels. Would be nice to update the river page with the new beta.

I don't know if it's a new gauge or datum shift. Think the best we can do is try to find the correlation btw new and old. Springtime flows should help providing the seasonal stability to match with our sf gauge historical records. Anything more and I'd just be guessing...
