Gauge at S Yuba bridge was 26". No dreamflow report to correlate that to on Sunday. Was my first run, so can't compare to other levels. I could believe it was 750 cfs (report from Saturday) or maybe a bit more. Great run.

The Cisco gauge starting reporting again; the 2pm flow was 693 cfs. What time on Sunday did you measure the 26"? If you can supply that information, I'll interpolate or whatever to find the corresponding flow with quite reasonable accuracy.

Chris,
It was about 10 or 10:30am when we were at the gage.

Awesome. Flows were very close to 750 cfs at 10/10:30 am ... great estimate, Jay. So we have a solid data point: 26" (stick gauge at the concrete bridge) correlates to 750 cfs (PG&E's Cisco gauge).

If we keep creating data points, soon we can put together a rating table for the put-in gauge ... so bring on the data points if you'd like to be involved, though please don't forget to record the time too, as accurately as you can. The more accurate our data points, the more accurate the rating table, naturally. Usually (like in this case) it's not super critical, but sometimes the flow is changing so fast even 15 minutes is significant.
