This blows. I think that they changed the streambed by the guage when they put the boulders in for fishing this spring. The new rating table will be the conversion from gauge height into flow, no idea how much it has changed.
The good news is that there are lots of gauges in the clear creek drainage. The next clear creek guage upstream is the gauge at lawson. Tributaries that are gauged between lawson gauge and clear creek gauge are: chicago creek, fall river, and north fork of clear creek. If you sum up cc @ lawson + the other 3 tribs you are withing 95% of the clear creek at golden flow from may 15 - june 30 last year. Between may 1- and may 15 the additive numbers were low for last year due to low elevation snowmelt that drove early high flows.
So until then you can just add the guages up and get the total flow. The data is available at the colorado department of water resources web site. I look at the clear creek section of the south platte basin to get the data.
Maybe the eddyflower guys can program a virtual golden gauge that sums up the numbers for us so we don't have to do the math everyday.
Looking forward to a good season on clear creek this year!
