Ora Bridge Construction Beginning Soon

Construction on Ora Bridge is scheduled to begin this month as part of a full replacement and relocation of the bridge. Fremont County is committed to protecting fishing access at all times during construction and HFF will be monitoring water quality above and below the bridge. 

At times, construction could require that the existing bridge be closed for a couple of weeks at a time. Vehicles may have to take a detour down to Vernon Bridge. Replacement of the bridge is a significant project and current timeline for construction is March 2019 - October 2020.

Stay tuned for additional information regarding water quality and construction progress.

Celebrating HFF's 35th Anniversary:  Lessons Learned

In honor of HFF's 35th Anniversary, each week in March and April we will share significant findings or key facts we’ve learned about the river over the past 35 years. Get ready for a crash course in Henry’s Fork trout habitat, fish passage, macroinvertebrates, hydrology, Island Park Reservoir, water quality, economic value of fishing, and water management.

PART 1: Ranch Habitat

1) Winter survival of juvenile rainbow trout is the most significant factor limiting the population in the reach from Island Park Dam to Hatchery Ford. 
2) Almost all available winter habitat is in the Box Canyon because macrophytes (rooted aquatic plants) don't provide winter cover.
3) Higher flows below Island Park Dam lead directly to an increase in the amount of bank habitat, which leads directly to an increase in the number of young trout that survive the winter.
4) Putting permanent structures like Christmas trees in the river were ineffective because they simply filled up with sediment.
5) Physical habitat structure in the Harriman reach during the fishing season is provided by rooted aquatic plants, which increase water depth at a given streamflow rate, and adult rainbow trout seek out deeper water.

Our Annual Boise Reception is Almost Here

Join us for our annual Boise Reception on Friday, March 29, 2019 at 6:00 PM.  The reception will be held at the Stueckle Sky Center at the Albertson's Stadium in Boise, Idaho.

We are privileged this year to have Lonnie Allen as our keynote speaker. Lonnie is the owner and is hands-on in the operation of Three Rivers Ranch.  She is an expert angler and world traveler.  Under her care, the business has won Orvis Lodge of the Year.  In addition to the lodge, Lonnie has 4 full service fly shops across Idaho, and was nominated in 2016 for the Orvis Lifetime Achievement Award.

Special Highlight​​​​​​​

South Fork Initiative Off to a Running Start

Here are a few of the projects the South Fork Initiative has been involved in so far this year.​​​​​​​

Science and Technology

Macroinvertebrate sampling: The South Fork Initiative conducted our first annual macroinvertebrate sampling on the South Fork last week. Sites were sampled in the Upper Reach (Dam to Conant), Canyon Reach (Conant to Heise), and Lower Reach (Heise to confluence). The samples will be analyzed and a report provided with raw data and summary statistics later this summer. Special thanks to the volunteers that helped with sampling, and to South Fork Lodge & Outfitters for helping launch the raft and run shuttles.

Water quality monitoring:  With help from The Lodge at Palisades Creek, the South Fork Initiative was able to install the housing for the first South Fork Snake River YSI Exo 2 sonde. As HFF members know, sondes are high-tech water quality monitoring equipment that collect data on temperature, turbidity, conductivity, dissolved oxygen, blue-green algae, chlorophyll, and other important water quality parameters at 15 minute intervals. We anticipate acquiring the first South Fork sonde in the next few weeks and the pre-installed housing will allow us to deploy the sonde without the complications of working in high flows. The SFI plans to install three sondes along the South Fork this year and will continue to build out the water quality monitoring program over the following 2-3 years.
Outreach and Education
South Fork Initiative Project Manager, Bryce and HFF Conservation Technician, Kam led a workshop demonstrating tools HFF uses (and SFI will use) to measure water quality and quantity!

The South Fork Initiative continues to share information regarding flow changes out of Palisades Dam, snowpack updates, and information regarding projects on the South Fork. Communications are shared through SFI Facebook, Twitter, Instagram, and via email. To receive these updates via email, contact Bryce.

Thank You for Making Our Salt Lake Reception a Success


Our Salt Lake event was a great success! It was a wonderful evening with friends coming together to support a great cause. Thank you to our Salt Lake chair, Pete Taylor and planning committee for making the event happen. The room was filled with just a little over 220  in attendance. A special thanks to keynote speaker, Tom Dixon who touched the audience with his special Henry’s Fork experiences.

Our work would not be possible without the generosity and support of our members. Thank you for another amazing year!
