Clear Creek gauge off?

I just finished black rock. Ive run it dozens of times and thought it was 750-800 cfs, but the gauge says 1080. Anyone get a similar feeling?

On friday I thought the gage was on, or maybe 50 cfs low, but pretty close. My guess is based on which rocks are submerged, so should be fairly accurate. Perhaps you've just gotten better at boating!

As much as I'd like to stake a claim on what a sicko high water hard man I am, I've been wondering if the gauge is reading high as well. That's my perception on the water and it seems like the differential between the Lawson gauge & Golden gauge is higher than I'd expect for this point in the season. Then again, maybe now that it's down from 1700 my perspective is out of whack.

There was a measurement on 6/2 that showed Golden was reading somewhere around 130 cfs high. Usually when that happens and it's corrected you see a vertical line to adjust. I haven't seen the adjustment yet, so presumably it's still off.

I've noticed the Xs in the graph on Bc as well, and no flow up with the vertical line indicating recalibration.

I assume it's then remains off by the same amount as the x differed from the graph. More likely a percent than an add/subtract would be my guess.

That's weird. I wonder if it takes them a bit to re adjust the automated readings. Because I always record flows I've noticed that the recalibration always gets applied retroactively as well.

The margin of error on their manual readings I bet is pretty high, especially at high water. They're basically counting clicks of a turning anemometer, and then extrapolated based on depth and velocity.

I haven't paddled CC much over 1300 cfs over the years, as it has rarely even gotten there, so I think it'd be hard to gauge at those flows if it's off based on feel. Plus, I bet my own boat feel when getting on the water has more to do with whether I feel it's high or low as compared to the gauge then any actual flow difference.

Those little clicker things are a pretty accurate measure of velocity, but just that. They hang me from a cable or bridge and take many readings along both width and depth. I suspect they get very close to real time flow.

So the Lawson gauge is reading 30
CFS more than Golden. I don't recall that one ever exceeding golden in years past. Is there a new diversion or do folks think the Golden gauge is off?

Don't think necessarily. Could be water going into groundwater.
