April 1 Snowpack Below Long-Term Average in Upper Henry’s Fork  

On April 1, the traditional date of peak-snowpack measurements around the western U.S., snow-water equivalent (SWE) in the upper Henry's Fork watershed was at 106% of the 1981-2010 median. However, this value was only 98% of the long-term mean, based on records that go back into the 1930s at some sites.

Extensive loss of snow at Island Park, Crab Creek and Pine Creek Pass during the middle of March greatly reduced the amount of snow on the ground on April 1. Seasonal SWE accumulation peaked 10 days earlier than median at Pine Creek Pass and 15 days earlier than median at Island Park. Snowmelt during March contribute to high streamflows over the past few weeks, but that water will not be available when we need it most during mid- to late-summer.

Thus, water supply for the spring and summer will be below average in the upper Henry's Fork (upstream of Ashton), despite what appears to be a "good" snowpack.

Idaho Gives Only 3 Weeks Away - Are You Ready? 

Our 2017 Idaho Gives goal is to raise $40,000 toward our Stream Gage Project. Optimal management of water and fisheries resources in the Henry's Fork requires real-time knowledge of streamflow.  The U.S. Geological Survey (USGS) stream gage network is sufficient for delivery of irrigation water and accounting of water rights, but real-time gaging is lacking locations where it could specifically benefit fisheries.  Unfortunately, the number of stream gages operated by USGS is decreasing, not increasing. Therefore, HFF has decided to install and operate its own stream gages at locations that will complement USGS stations.

Every donation made to the Henry’s Fork Foundation will be matched dollar for dollar by generous members of the Foundation’s Board of Directors, up to $20,000! 

And for every $50 you donate, you will receive a raffle ticket for a chance to win a Flycraft Stealth Package, valued at $4,000!

You can and your donation will still be doubled AND count towards Idaho Gives on May 4!

Henry's Fork Days XXXIII is Right Around the Corner  


What You Might Have Missed: Special Highlight

Timing of snowmelt: Why is it important and what do we know about it?

by Rob Van Kirk

  • Timing of snowmelt runoff affects river ecology, trout behavior, fishing experience, and mid-summer streamflow in natural and regulated river reaches.
  • Runoff timing is most strongly influenced by April-June temperatures (warmer = earlier runoff) and April 1 snow-water-equivalent (SWE; more snow = later runoff).
  • Since 1930, runoff timing in the upper Henry’s Fork has displayed a parabolic (upside-down “U”) trend over time, with the latest runoff occurring in the 1970s.
  • Date of 30-day peak streamflow in the upper Henry’s Fork in 2015 and 2016 ranked 2nd and 9th earliest, respectively, in the last 87 years. Earliest runoff on record occurred in 1934.
  • Over the past 30 years, mean April-June temperature at the watershed’s snow survey sites has warmed at 1.29°F per decade. All other factors being equal, this moves the 30-day peak flow window 5.4 days earlier each decade. Global climate models and data predict continued warming over the next few decades, so we can expect continued earlier runoff.
  • Runoff timing is poorly predicted by conditions in the month of March, so it is too early to make precise predictions of runoff timing in 2017. However, rapid loss of low- and mid-elevation snow since March 10 is greatly reducing the amount of snow on the ground. Thus, we are sure that runoff will be earlier than I would have predicted two weeks ago. Streamflow conditions will most likely be better than last year but not nearly as good as they could have been had the robust early-March snowpack stuck around until the beginning of April.

Thank You For A Successful Boise Reception 

Thank you for making our Boise event a success! It was a wonderful evening with friends coming together to support a great cause. Thank you to our Boise co- chairs, Jerry Nielsen and Paul Schmidt, and planning committee for making the event happen. Special thanks to our speakers, Jack Roberts and Dr. Rob Van Kirk. With record attendance, an energetic live auction, and more, it was definitely an evening to remember. Our work would not be possible without the generosity and support of our members. Thank you for another amazing year!

Seeking Volunteers
