Henry’s Fork August 2nd, 2022

Throughout the river early AMs and evenings remain the best fishing. Thinking of trying the river during weekends? Be ready to share it with recreational floaters.

Headlines from Dr. Rob Van Kirk’s Henry’s Fork drainage report compiled yesterday are below.

 Headlines:

• The daily maximum temperature yesterday was the warmest since July 26 of last year, but cooler temperatures are expected over the next week.
• Diversion and natural flow both dropped a little yesterday, increasing stream flow in lower Fall River and lower Henry’s Fork.
• At 240 cfs, current Crosscut Canal delivery to the Teton River is meeting irrigation demand and stream flow targets there after exchange well pumping was reduced a few days ago.
• Island Park Reservoir is 65% full, compared with 67% full. Outflow reductions are possible this week, depending on stream flow and diversion response to rain and reduction in outflow from Grassy Lake.
• Flow out of Grassy Lake Reservoir will be reduced resulting in a 100 cfs flow reduction in Fall River.
