Henry's Fork

Headlines from Dr. Rob Van Kirk's water status report of yesterday for the Henry's Fork drainage:  

• With the first month under our belt, water year 2023 started right where 2022 left off: slightly warmer than average, precipitation at 91% of average, and natural stream flow among the lowest on record.
• The first very cold weather of the fall arrives tomorrow, and heavy precipitation is expected to begin Saturday and last well into next week.
• At an outflow of around 130 cfs, Island Park Reservoir gained 493 ac-ft yesterday and is 52% full, compared with 55% full on average.

Upcoming weather may make fishing the upper river a challenge. Fishing on the lower river should not be as challenging with respect to air temperatures but stronger winds will make dry fly fishing tougher and diminish hatches.
