Henry’s Fork, August 6th, 2022
Throughout the river Early AMs and evenings offer the best fishing as well as the lowest number of recreational floaters. These folks are most numerous during weekends with Box Canyon, Warm River to Ashton, Ashton to Chester and the river below St. Anthony being where they are most concentrated.
For now, consider minimizing visits to the the river from Ashton Dam to Chester to give trout a break from tough recoveries through being played in warm water..
Warm River to Ashton offers good fishing especially for those concentrating presentations toward banks. We suggest hopper patterns and such as chubby chernobyls on top to drift suspended nymph patterns of choice in the water column below.
Headlines from Dr. Rob Van Kirk’s Henry’s Fork drainage water report compiled yesterday are below.
Headlines:
- Yesterday’s mean temperature was 3 degrees F below average, and a few showers were recorded in the Teton sub-watershed.
- Natural flow in Fall River and Teton River continues to benefit from the effect of Tuesday’s rain, while diversion dropped by another 7% yesterday.
- Outflow from Island Park Reservoir was reduced to 900 cfs yesterday, and additional reductions are likely over the next week.
- Fishing conditions: Streamflow across the watershed is well below average for the date, turbidity is average in all stream reaches, and water temperatures have likely peaked for the year.
