We continue to try to share as much information as possible in as many ways as possible, to try to reach everyone who might be interested. This includes our Annual Reports, Newsletters, e-newsletters, emails and social media, etc.(but find a full list of resources below). Blogs like this one are another way we can try to concisely share updates on the work we do and our impacts (i.e., our annual "Top 10 Accomplishments" blog).
We've been asked a few times recently about the types of programs happening this year and what impact they might be having on the fishery, so we'll take this opportunity to share some highlights ahead of the end of the year. For more in-depth information on these projects and programs, check out our quarterly newsletters.
Some of HFF's ongoing long-term projects or programs*:
*NOTE: this is not an exhaustive list
- Water sampling, water quality monitoring, and live data website - Aquatic insect monitoring and working with partners to achieve managed spring freshet flow - Farms & Fish Program

- Youth Education: Trout in the Classroom, Youth on the Fly and local school field trips
- Fish ladder monitoring and maintenance

What's the impact for fisheries?
Water conservation -- via programs like Farms and Fish, Precision Water Management and the lower Henry's Fork PhD research -- have increased winter outflow from Island Park Dam by an average of 115 cfs since we began our efforts in 2018. This increased the number of two-year old fish entering the Box Canyon population by 775 (16%) in 2019, 855 (23%) in 2020, 310 (8%) in 2021, and 380 (13%) in 2022. Tracking these cohorts of fish through time, water conservation has increased the total population by 7% in 2019, 14% in 2020, 11% in 2021, and 21% in 2022. Even at the current level of water savings, the long-term average contribution to the population is 980 fish, which will increase the population by an average of 15% relative to pre-2018 levels.
