Henry’s Fork, August 16th, 2022
Terrestrial insect patterns are the best bet for action almost everywhere on the river during daytime hours.
Headlines from Dr. Rob Van Kirk’s water report submitted yesterday for the Henry’s Fork drainage follow.
Headlines:
- After a dry day, water-year precipitation stayed at 91% of average, ranking 12th driest out of the last 33 years.
- Natural flow is receding from the effects of Saturday’s rain, but proportional decreases in diversion are keeping lower-watershed streamflow ahead of target flows.
- Updated data show about a 5% improvement in natural flow upstream of Island Park Reservoir since this time last year.
- Water quality: Peak water temperatures were about where they were on Sund
