I put together a correlation based on the USGS daily peak data and the snowpack % of average Snotel data from the two links in this thread. I used 1997 through 2005, as the basin snowpack averages were not available before 1997. I ended up taking a few obvious outlyers for high peaks (probably heat wave?), and the rest of the data had a 99% R squared, meaning the data fit the curve well. The equation is Peak Rate in CFS (daily average peak rate) = snowpack % of average (max number from snotel monthly basin average) * 7.69.
If clear creek stays at 171% of average, this would mean a peak rate of 1315 cfs. If the snowpack hits 200% with good spring snows, the peak would be 1538 cfs. If a big heat wave comes and melts it all at once, I would add 30-50% to the peak rate.
The big question is how much more snow will come. It seems that in big snow years, the snowpack increases in % in the spring. So I will take my stab at things, and guess 1500 cfs for clear creek's peak at golden.
I don't know how to post the graphs and spreadsheets on the buzz, but if anyone wants to see it, email me at email@example.com
