 Past Volunteer Activities

Fence Repair - Harriman Ranch

In the early days of the Foundation grazing damage to the streambanks in Harriman State Park inspired a signature HFF project: the installation of riparian fences along the river from Last Chance to Pinehaven. Every summer, the fence goes up and every Fall it comes down. So, thanks to the cooperative effort between the Foundation, Harriman and the Forest Service, after 25 years, the cows and fence are still there.


Highway 20 Roadside Cleanup

Thanks to all the volunteers who helped with the Henry’s Fork Foundation roadside cleanup day. Many volunteers were in Island Park on June 29 to help clean up the road between Elk Creek and Mack’s Inn.

Volunteers (not in order as pictured): Julie Coley, Gin Russell, Meghan Bartley, Paul Beebe, Laura Sass, Lee and Phyllis King, Bob and Ellen Stantus, Val Zupsan, Caroline Bovay, Adam Costello, Tess Hayden, Annabelle Glass, Anne Marie Golz, and Drew Stricklan.

Staff Members: Melanie Sessions, Kim Ragotzkie, Jim De Rito, Anne Marie Emery Miller, Susan Steinman.

The next scheduled cleanup for Highway 20 will be this fall. Contact the HFF office if you are interested in volunteering.

Willow planting - Henry's Lake Outlet

The Henry's Fork Foundation organized an effort to plant willows along the banks of the restored Henry's Lake Outlet channel. Many volunteers pitched in their time and energies to accomplish this effort.

Telemetry study support

This study is evaluating trout movement, migration, and habitat use in the lower Henry’s Fork. Little to no scientific information has been collected about the trout populations in this part of the river that has been altered by diversion dams and irrigation canals. This multi-year effort seeks to understand the factors that govern trout distribution and abundance.

Buffalo River fish counts

The recent installation of a fish trap to capture those moving downstream at the hydroelectric project is being used to quantify how many are returning to the Henry's Fork. During the first two weeks of operation, more than 40 rainbow trout were captured, measured and released downstream.

Henry's Fork Day event assistance

Henry's Fork Day would not be the annual event that it is without the dedication of its tireless volunteers.
Henry's Fork Day XXVIII will be held on Saturday, June 16, 2012 on the banks of the Henry's Fork of the Snake River in Last Chance, Idaho. The day's events included the  HFF Annual Meeting, fly casting competition, silent auction and a prime rib or chicken dinner followed by a live auction with auctioneer, Will Godfrey.
