Why aren’t anglers seeing big fish in the Ranch? Are hatches changing?
Thank you to all of those who attended this year’s annual Henry’s Fork Watershed Council tour! Participants toured the Last Chance…
Fremont County operates a wastewater treatment facility (WWTP) on Forest Service ground in Last Chance. With the continued growth of…
As summer transitions to fall, we’re reflecting back on where we were as of the start of the year. Originally published January 23, 2024….
What’s the difference between turbidity and sediment? Turbidity can be: Mineral sediment mobilized from reservoir bottom or suspended in…
Summertime outflow from Island Park Reservoir is lower (not higher) than it was in the “glory days”.
Do water temperatures on the Henry’s Fork get too hot to fish and should there be hoot owl closures?
UPDATE: With only one month left in the 2024 water year, let’s take a look back at Water Year 2023, and get a preview of the types of…
This year, the Henry’s Fork Foundation’s (HFF) annual membership meeting was hosted on June 5th in Island Park. Dr. Rob Van Kirk gave an…
A continuation of the discussion around a proposed “airpark” and new Marriott in Henry’s Lake Flats.
Information about invasive species stickers, watercraft registration, outfitter licenses, and river recreation regulation.
UPDATE: After 10 years of studying Island Park Reservoir, we thought we had seen just about everything possible, but the current event is…
To help anglers plan their fishing day, the HFF launches a new way to visualize water clarity by showing how “brown” the river might be.
Mick Mickelson and Mike Lawson talk about the 1980s and what prompted the formation of the Henry’s Fork Foundation in 1984.
Rather than a typical “hatch chart”, HFF’s hatch timing calculations are based on accumulation of thermal units in the aquatic ecosystem….
Learn about how streamflow is managed, who the key players are, and how water management interacts with your river experience.
Increasing spring and summer air temperatures have a doubly negative affect on water quality.
Fish are affected by life-history specific streamflow and habitat characteristics that are not simple, direct functions of water supply.
In recent years, HFF has expanded its work beyond the Caldera. Why? All roads lead to Island Park Reservoir, the center of the universe.
Water use + management in the Henry’s Fork watershed have much larger effects on streamflow than any changes due to precipitation type.
When snow makes up a larger fraction of total precipitation, prediction of irrigation-season water supply is more precise
