HFF's Top Ten of 2019
At the end of each year, HFF takes a moment to reflect on all that was accomplished for the Henry’s Fork in the previous 12 months. To keep the tradition going, HFF is taking a look back at the "Top-10" programmatic accomplishments and events worth celebrating from 2019.  

1.  2019 was the Henry’s Fork Foundation’s 35th Anniversary
2.  With only average water supply, precision management turned an average year into record reservoir carryover and well above average winter flow for trout
3.  Box Canyon trout populations 4th highest since IDFG record keeping began
4.  Kokanee in the upper river 
5.  HFF’s programmatic work expands to the South Fork in South Fork Initiative’s first full year 
(tie) 6.  Crucial Work Underway to Enhance Upper River
(tie) 6. First of Its Kind Research on Lower Henry’s Fork
8.  Favorable weather – 2019 springtime temps equivalent to average temps expected in spring of 2003
9.  HFF partnered with the US Forest Service on a recreational use capacity study of the Big Springs Water Trail
10.  HFF’s model of conservation at home and abroad

What You Might Have Missed - Special Highlight

HFF Partnered with the USFS to Assess Recreational Use Capacity on Big Springs Water Trail

Many anglers can attest to the beauty of the Big Springs to Mack’s Inn reach, also known as the Big Springs Water Trail, with its towering pine trees and resident moose. However, angler concerns regarding floaters in that stretch prompted a partnership between the US Forest Service and Henry’s Fork Foundation. In 2019, HFF conducted a recreational use capacity study to assess if floater use is exceeding capacity of facilities and to determine both floater and angler satisfaction with their experience. The study ran from Memorial Day to Labor Day 2019 and provided some unique insights including: 

  • Total use estimate was 37,187 floaters. 
  • 18 percent of floaters used Mack’s Inn transportation. 
  • 90 percent of floaters rated their experience as ‘very good’ or ‘good’. 
  • Over half of all floating devices used were kayaks, followed by tubes (about 20 percent) and canoes (about 10 percent). 
  • Anglers’ experience was worse than desired regarding size of fish caught, condition of fish habitat, and number of non-angling floaters on the river.

To read the full report, click here.

HFF has shared the full report with the Forest Service to help inform future management of floaters, but HFF is also part of a study of the factors that might be impacting size of fish and condition of habitat in that reach. Hopefully, results can help improve fishing conditions in future years. To learn more about this study and HFF’s programmatic work in the upper river, email Rob at rob@henrysfork.org


Thank You for an Incredible Month End

Thanks to your generosity and Patagonia's incredible gift of matching all donations made on their Patagonia Action Works page at year end, HFF had a record year of fundraising for crucial programs to conserve the Henry's Fork.

It is thanks to members like you and organizations like Patagonia that we are able to continue to innovate and pioneer programs that will help ensure a healthy future for the wild trout fisheries of the Henry's Fork. Your dedication to conservation and passion for the Henry's Fork makes it all possible.

Thank you!
IDWR Island Park Reservoir Enlargement Website Launched 
The Idaho Water Resource Board (IWRB) is evaluating options for increasing water supply, including an alternative from the Henry’s Fork Basin Study, Island Park Reservoir Enlargement. This would involve using flood surcharge space in the reservoir that is already within USBR’s existing authorized easement around the reservoir to provide additional storage capacity. IWRB, in consultation with USBR, has now completed an analysis of potential impacts to property and infrastructure. 

Study information regarding the Island Park Reservoir Enlargement Project concept is available online on the Idaho Water Resource Board’s (IWRB) website. The website allows users to navigate to specific areas or properties with additional resources found under the ‘Resources’ tab. 

Any updates or meeting notifications will be posted on the website

There are a lot of subtleties to this issue, so we will only speak to impacts on fisheries. With appropriate administrative conditions, increasing the capacity of Island Park Reservoir has the potential to benefit fisheries above the reservoir, in the reservoir, below Island Park Dam, and in the lower Henry’s Fork. Research and monitoring shows that water in the river downstream of the reservoir is cooler when the reservoir stays more full, and this temperature advantage would be greater if the reservoir were a couple of feet deeper. A larger reservoir would provide more habitat for reservoir fish, which migrate into the upper Henry’s Fork, and improve water quality in the reservoir and in the river downstream.
