Your gift fuels the early science and conservation needed for next year and beyond.

The DNA of A River                                    This fall, your gift helps HFF use new science to understand changing hatches, protect the Henry’s Fork, and guide the next generation of river conservation. The Henry’s Fork has always been read by careful observers. Anglers watch the water for rising forms. Scientists track temperature, turbidity, and flow. Field crews study the life beneath the surface. But today, some of the river’s most important questions are harder to see. Aquatic insects may be abundant on the river bottom, while the hatches anglers experience tell a more complicated story. Are insects emerging earlier? At night? In different places? More sporadically? Are warming temperatures changing the rhythm of the river? HFF is working to find out. This year, HFF and The Salmonfly Project are pioneering a new application of eDNA on the Henry’s Fork: using environmental DNA alongside traditional insect monitoring and emergence traps to better understand PMD hatch timing. Environmental DNA, or eDNA, allows scientists to detect tiny traces of genetic material left behind in the water by insects, fish, and other organisms. In a single water sample, the

If you’ve fished the Henry’s Fork lately, you’ve seen it⏤low flows, cloudy water, shifting hatches. The Henry’s Fork remains a world-class trout fishery, but it’s feeling the strain. Thanks to anglers like you, HFF’s Smart River ConservationTM is meeting these challenges head-on: improving winter flows that add 500 more trout to Box Canyon each year, conserving 24,000 acre-feet of water to keep the river cool, and delivering the real-time science that powers the Daily Water Report you trust. But as the river changes, so much our work–and your support makes it possible. This Giving Tuesday, December 2, your gift will go twice as far⏤HFF’s Board of Directors is matching all gifts up to $29,000. Together, we can keep the Henry’s Fork resilient, fishable, and thriving for seasons to come. 🎣 Mark you calendar and get ready to give back!     GIVING TUESDAY GIVING LEVELS AND INCENTIVES $50 – Loon Outdoors Nocturnal Headlamp  $100 – Custom HFF YETI Shot Glasses $250 – Custom HFF YETI Pitcher $500 – North Fork Nets Wading Net $1,250 – All Incentives Listed Above $2,500 – Green Drake – Scott Centric Rod 4-7wt (freshwater) OR Scott Sector 6-12wt (saltwater) OR Hatch Iconic Fly Reel (3-11+)

It’s a shared place, a shared responsibility, and a community that shows up when it matters. For more than 40 years, that commitment has driven science, partnerships, and steady progress. Today, it’s carrying us into the next phase of that work: DIRTT—Developing Infrastructure to Reduce Temperature and Turbidity. Years of research, assessment, and evaluation have brought us to this moment. Designs are advancing, partners are engaged, and meaningful solutions are coming into focus. Now, the work shifts from understanding the problem to action. The DIRTT Action Fund is how that action happens. This fund allows us to move decisively—to advance infrastructure when windows open, demonstrate readiness to partners, and turn proven science into real improvements for water quality and fish habitat. This is how a strong community turns knowledge into action—and action into a healthier, more resilient Henry’s Fork. Because amazing days on

On Saturday, June 19, 2027, join hundreds of fellow supporters under the big tent for an evening of community, conservation, and celebration. Fisherman’s Access – Last Chance, Idaho MORE INFORMATION TO COME!
