Snake River Runoff report

June 4th, 2014

The runoff in the Upper Snake River Basin is in full force.  After seeing peaks in the Snake River canyon of over 22,000 cfs, on May 31st,  flows have subsided to just around 18,000 cfs as of today.   The flows coming into Jackson Lake at Flagg Ranch reached over 10,000 cfs, which is HUGE for this area, and are now in the 6,000 range.  The last couple weeks of May were unseasonably warm and that brought down a lot of snow quick.  The jury is still out as to whether or not we will see flows reach these levels again, but, there is no doubt that there is still a good bit of snow to come down and the Snake will be muddy for the month of June and into July, how late into July depends on how hot Mother Nature is!  The current Snotel data shows the Snake basin at 112% of its average for this date.  Meanwhile, up at the Jackson Lake Dam, controlled flows as of today are coming out at 2,000 cfs and are expected to rise to 5,000 for a little bit, then to 6,000 for one day, and gradually work back down to 2,500, where they are predicted to stay for the summer.  This will translate into a terrific summer of fishing.  We will update the Snake Report as news develops, stay tuned.
