Henry’s Fork, October 25th, 2022

Headlines from Dr. Rob Van Kirk’s water analysis report taken yesterday for the Henry’s Fork drainage are below

• Wet, cold weather continued yesterday, keeping monthly precipitation at 98% of average.
• Natural flow increased to 89% of average.
• At an outflow of 157 cfs, Island Park Reservoir gained 460 ac-ft yesterday and is 50% full, compared with 52% full on average.
• Water quality: Turbidity dropped at all locations yesterday; high phytoplankton growth continues in Island Park Reservoir.

Flow of only 157 cfs out of Island Park Dam makes wading in Box Canyon quite easy, and presenting streamers very effective. Rubber legs and large nymph patterns also work well. We also have great weather for BWO activity throughout the river. Bundle up and don’t put away that floating line yet!
