Streamflows

More snow nerd stuff.  Actually, the attached links bridge my two favorite passions, snow / skiing and river running.  The first link details streamflows for most major Colorado rivers and creeks.  The second link specifically details flows on the Snake River.  Water on the frontside of A-Basin drains directly into the the North Fork of the Snake River which drains into the Snake River.  Water in Montezuma Bowl drains directly into the Snake River.  This link is for a gauging station named "Snake River near Montezuma, CO".  The station is on the main stem of the Snake just below its confluence with the North Fork.  In the 72 hours from midnight on May 10 to midnight on May 13, you can see streamflow tripled from 20 cfs (cubic feet per second) to 60 cfs.  You can see that streamflow really increases during a warm day until about midnight and then drops off a bit as night time temperatures cool off and snowmelt decreases.  It is interesting right now that each day's peak flow is higher than the previous day's peak. Clearly, water is on the move.  These are good clues for the snowpack and a great planning tool for your next river trip.

Gee, Al, I usually love your posts, but this one is so esoteric. Snow actually melts slower at lower temps? Who would have guessed. Stick to skiing big guy

Sorry Seth. I thought the link to temps, snowmelt, streamflow, etc. was kind of cool, but you might be right. Thanks for the feedback. Al

Seth......kinda harsh.....Al, if you want to post snowmelt info and all kinds of nerdy stuff then do it. Some will find it helpful and others not so. Even if some thin you're stating the obvious, why not? Whats obvious to come isn't obvious to all. Kepp posting anything and everything that is Basin related!

No.. No.. if you have a passion.. and can share that knowoledge with others... absolutely do it.... if you touch one person.. (me) you are making a difference.

Lots of us like to hear about what goes into making the decisions on when to open and close. Rather see the process in work then having the mountain closed based upon a date posted back in October regardless of actual conditions in April/May.
Keep on posting that info Al.

Gee seth, how many ski areas have blogs where you get the inside scoop on terrain status and mountain happenings, strait from the COO himself. don't discourage that big guy... i thought the link was cool

Al-

Keep every and all information coming, and thanks for passing along the websites. It's great to see everything you guys monitor to determine the snow pack. Do you have a guess on when lake reveal will start to show?

Nice work, Al. All very interesting because it's about what is actually happening in the mountains right now, what is happening to the actual snowpack.

Don't listen to Seth.

snowmelt and streamflow are important - A-Basin makes snow in the early season from someplace.

Thanks for the info Al. The graph was very interesting. I followed the links, reposted it, and mailed to my friends down in Dillon/Silverthorne who I'm sure are interested. Wonder how fast the reservoir is going to fill. It has a ways to go!
