I was trying to plan a boating/climbing trip also, and dug up some historical info to compare to this year. Hopefully someone can tell me if I got the wrong guage/snotel sites.
First, I pulled up the closest snotel sites and got the peak SWE for the last 4 years. Red Pine ridge and mammoth seemed to be the closest sites with several years of data. 2010 and 2012 had similar SWE to 2013 for both sites.
Red Pine Ridge Snotel 2013: 10 SWE, 2012: 10 SWE, 2010: 13 SWE
Mammoth-cottonwood 2013: 14 SWE, 2012: 11 SWE, 2010: 17 SWE
Here is a plot of Joe's Valley reservoir discharge for the last 4 years (attached) from Emery Water Conservancy District: Cottonwood
. The highest flow it shows in 2011 is 500 cfs, but Cutch ran it at 1200 cfs and I thought I ran it around 700 cfs, so there might be a better guage?
Either way, flows don't look good, but this shouldn't be a surprise to anyone. We are still going climbing, but will probably be taking innertubes instead of kayaks.
