To answer your original post in this thread, I would estimate that flows will be somewhere between 700 cfs and 1100 cfs, with the most likely flow being between 800 and 900 cfs. I am basing this guess on the data from the 2002 season which was the most similar season to this one in regards to snowpack/snowmelt/flows. USGS Surface Water data for USA: USGS Surface-Water Daily Statistics.pdf
In 2002, the highest flow was around 886 cfs.
In response to your statement about below 1400 cfs being "bony". I would have to say that it is all relative. Above 1400 or 1600 cfs could be considered the beginning of "medium" flows, and above 3000 cfs might be considered "high" water for kayaks that are just running the river. However, in relation to holding the Gore Canyon Race, these parameters do not apply. The Gore Canyon Race is an event that includes kayaks and rafts. 1400 - 1500 cfs is the maximum flow that the permit/insuring agents will allow for the race to be staged. Above 1500 cfs running the canyon in a raft, and in my opinion, racing in a kayak is considerably more difficult. Carnage at these levels is much more probable and swims could be disastrous.
In addition, in all but the higher than average snowpack years, flows above 1500 cfs are no longer that common.
If a 800 - 900 cfs Gore Race level is not that much "fun" for you, perhaps you would have more fun on the Poudre River on Aug 18th. The flow on the Poudre should be awesome.
