The Henry's Fork in 2022
What You Might Have Missed
We share a lot of information about the river throughout the year, and we know it can be a lot. In case you missed it, here are a few highlights from 2022.
Drought and a Changing Climate
Water Year 2022 was the driest since 1978 in terms of water available in the river for fish (natural streamflow).
The Henry’s Fork Watershed was categorized in “extreme” drought by the US Drought Monitor in summer 2022, and has been in a longer-term pattern of drought for the last 20 years.
Impacts on Fishing Conditions
As forecast last spring, low fish population, delayed hatch timing, continuously cold weather in the spring, continuously hot weather in July and September, low aquatic plant abundance, low insect abundance, high streamflow, and high turbidity combined to produce tough fishing conditions on the Ranch in 2022.
Given that water supply in 2022 was among the lowest in the last 90 years, the trout population is expected to remain low at least for another two years and EPT abundance (mayflies, stoneflies, caddisflies) for another year.
Full details on insect populations and fishing conditions are available in the full 2022 technical report, and also available in our newsletters, river update emails, social media and HFF blog.
What You’ve Made Possible
I really don't like to say it, and I know it's not a very inspirational message, but things would have been quite a bit worse without the crucial work you made possible in 2022. Record low water supply and changing climate had set up a very tough year.
However, our work with partners has measurably reduced the negative effects of drought, through improved fish survival and fishing experience, at a level unprecedented across the West. That is only possible thanks to your support.
Impact
112 cfs increase in winter flow from Island Park Dam
126 cfs reduction in summertime outflow
980 fish added to the Box Canyon population per year
25,000 acre-feet of water saved in Island Park Reservoir per year
Looking Ahead
We know our work is not done and we are driven to do more to not only conserve this fishery, but improve the fishing experience for all those who enjoy it.
If you have any questions or concerns, please don't hesitate to reach out to us. And browse our monthly e-newsletters, quarterly newsletters, social media, blogs, and more to stay in the loop throughout the year.
Sincerely,
