Henry's Fork Area Fishing Report

Last updated: July 2, 2009

By:Chris Lawson

The fishing is hot right now up and down the Henry's Fork. We have had far above normal precipitation throughout this month, but the weather has finally turned to summer. Our guide book is filling fast, so call us up and book your guide trip.

Some of you may not be aware of the latest news concerning invasive species stickers for all boats over 10 feet in length. For more information or ordering your stickers, please visit www.invasivespecies.idaho.gov or call 1-877-336-8676.


Upper Henry’s Fork - Box Canyon:

The Box Canyon flows have been a little below normal for the last few days. The flows are around 630 cfs.Very good fishing!! Try golden stones for dries. The most productive fishing is subsurface. Suggested patterns include black and brown rubberlegs (size 4 and 6), prince nymphs, tungsten zebra midges, and caddis pupae.


Upper Henry’s Fork - Harriman State Park and Last Chance:

Harriman State Park has opened as of June 15, 2009. Very good fishing. We have had very good hatches of Green Drakes mid morning to mid afternoon. We sill have some PMD's, so good spinner falls in the morning and evening. The big news is thick BROWN DRAKE hatches in the evening in Harimman State Park. If you are patient and move slow you can have a chance finding some very large rainbows in the 20-24 inch catagory. The fishing in Harriman State Park is not easy but very rewarding.


Middle Henry’s Fork - Riverside Campground to Warm River:

Good fishing on Golden Stones, Yellow Sallies, and caddis. If planning on visiting this stretch of water, bring a fly box with these respective patterns as well as a number of bead head nymphs to use as droppers.


Middle Henry’s Fork - Warm River to Ashton:

Same as above.


Lower Henry’s Fork - Ashton Dam to Saint Anthony:

This section is starting to slow down. We still have Lots of PMD and Flav spinner falls in the morning and evening. Mid day has been tough due to hot weather. The grey drake fishing has been good below Chester Dam. The subsurface fishing is still the most productive, but the dry fly fishing is starting to really turn on in the afternoon.


Lower Henry’s Fork - St. Anthony to the Confluence:

Flows are still above normal, but dropping fast . Grey drake fishing has been good in the moring and evening. We have had good fishing on Golden Stones as well in this section. We have seen some good PMD and Caddis hatches as well. Call for the latest updates. Streamers can be very productive in this stretch of water.


Henry's Fork Tributaries:

Many tributaries are still high and off-color, but becoming more fishable from week to week. We’ve heard reports of caddis action on Warm River.


The Madison River:

Flows below Hebgen Lake are dropping. Fishing in between the lakes has been good, but very crowded. Stay above Cabin Creek and use a variety of bead nymphs for most productive fishing. The SALMONFLIES are hatching around Ennis and will move up the river quickly.


Area Lakes:

Fish have started moving away from the shoreline on Henry’s Lake. Use brown and olive wooly buggers, eggs, and red colored nymphs. We’ve also heard of good midge fishing in the evenings on Hebgen Lake. No reports from Island Park Reservoir.


South Fork of the Snake

Flows out of the Palisades Dam have shot up to 23,000 cfs. Water conditions can be described as “milky green.” Some sections are not safe to fish. Nymphing with large black and brown rubber legs, tungsten bead head nymphs, and streamers will be your best options. These high flows are expected to start dropping throughout the week. Salmonflies should start in the next 10 days or so.


Yellowstone Park

The Firehole has been fishing great with PMD’s and Baetis hatches coming off throughout the day, and white caddis into the evenings. You may find the water high, but clear and very fishable. The Madison has become fishable with a few Salmonflies making appearances.


For more detailed information, please refer to our Hatch Chart. This is by far the most comprehensive hatch chart in the entire Yellowstone Region. Make sure to check out the hatch chart behind the aquarium in our shop.
