HF Hatch Report

The Henry’s Fork Foundation wants to learn what is hatching on the river (where and when) or if nothing is hatching at all. Your hatch observations will help us build a much-needed dataset, improve our hatch-timing tracker, and contribute to science-based river management for local fisheries conservation.

If you have questions about this effort, please email christina@henrysfork.org.

HFF's DIRTT Plan

HFF is launching the revolutionary DIRTT Plan (Developing Infrastructure to Reduce Temperature and Turbidity). We’re looking at massive-scale engineering solutions, as well as grounded, nature-based solutions to reduce the amount of sediment that is sent from the reservoir into the river downstream, and to reduce the temperature of the water coming out of the reservoir and flowing through the Harriman Ranch.
