If it flushed out then there's not much stopping the flow immediately upstream adjacent to the city of Nenana.<br /><br />GaryNL7Yhttps://www.blogger.com/profile/15874712728971005352noreply@blogger.comtag:blogger.com,1999:blog-4572286363399496963.post-57781331355689356902015-04-29T17:46:46.468-08:002015-04-29T17:46:46.468-08:00Eric, good observation - slower melt in the hills ...Eric, good observation - slower melt in the hills means slower river rises. It would be an interesting project to correlate river rises to temperatures and snowpack diminution, but I don't have the gauge data at my finger tips just now.<br /><br />The rapid valley melt-out may have pushed the ice out at Nenana a bit earlier than otherwise, but this is a difficult multivariate problem because there are so many other factors such as thickness and integrity of the winter's ice and local rates of melting from sun and warmth. It's difficult to isolate the influence of any one variable. But there's no doubt the breakup was early considering that temperatures were not that high.<br />Richard Jameshttps://www.blogger.com/profile/08313902028896263276noreply@blogger.comtag:blogger.com,1999:blog-4572286363399496963.post-4709441941352558482015-04-29T06:57:15.277-08:002015-04-29T06:57:15.277-08:00To correlate with the slower melting in other area...To correlate with the slower melting in other areas, the rivers aren't rising as fast as they normally would. Monday afternoon I noticed that the Chena near the airport started to pick up speed but didn't have a huge rise. And the amount of broken ice in the river is smaller than last year. I'm not complaining; this means less chance of flooding within town.<br /><br />Perhaps you could look at the various river gauge heights and compare them to where they normally would be and how fast they normally rise during breakup?<br /><br />And is there anyway to estimate how much snow we would have without Chinooks melting it away? Would the Nenana have gone out much later than it did?<br /><br />Thanks, Richard, for your posts on this blog.Eric Lundellhttps://www.blogger.com/profile/17914784378747801359noreply@blogger.comtag:blogger.com,1999:blog-4572286363399496963.post-35901459291715704042015-04-29T06:56:24.741-08:002015-04-29T06:56:24.741-08:00This comment has been removed by the author.Eric Lundellhttps://www.blogger.com/profile/17914784378747801359noreply@blogger.com
