Lower Henry’s Fork 3-15-12

Just an update on our earlier report from a few days ago. The water has discolored from Vernon Bridge downstream due to field runoff. This should clear in a few days as the low runoff melts and the ground thaws allowing the water to sink into the ground. This is probably a good time to use #4 and 6 Stonefly Nymphs and the streamer of  your choice.

Fishing on the Henry’s Fork has remained steady. Midges have been hatching and anglers are finding success on the surface. Nymphing is still the most productive throughout the day. Stonefly nymphs in a size 6 or 8 have been effective. Blue Wing Olives should start hatching anytime now. I would make sure I have BWO nymphs and dries in my box. Floating still seems to be a bit of a challenge right now because of the snow banks at the boat ramps, when this changes we will report on it.

Flow from Ashton Dam is slightly higher than normal, steady, and water has little discolor.   Snow depth limits access at some locations, but with warmer weather coming up look for easier approach to the river soon.  Right now “midging ” is a great way to find action throughout the lower river.   BWOs will start emerging in significant numbers soon.  If you prefer to fish streamers, a productive approach has been to swing, dead drift and quartering downstream, black or brown mohair leeches (#6 or #8) on a sink tip or sinking (keep it tight!) line.  It’s almost like presenting soft hackled patterns, but for some reason it’s an effective approach this time of year.

This post has been edited from the original post date of 3-6-12 when we made mention of the access difficulties at Ashton dam due to construction. Remember that the Henry’s Fork is closed from Ashton Dam downstream to Vernon bridge until May 26th. Sorry if we confused anyone in our  inadvertent attempt to change the fishing regulations!

I keep hearing really good reports from the Henry’s Fork. Fishing has definitely picked up with the warm unsettled weather we’ve had this past few weeks. San Juan worms and Rubberlegs have been the ticket. Look for fish rising on Midges on the warmer sunny days. I have heard reports of ice chunks below Chester Dam, however that can change in a matter of a few warm days.

Winter fishing is in full swing on the river. Mostly nymphs have been producing fish. I recommend 2 zebra midges under an indicator. I like to fish about 6 feet this time of year and use two contrasting flies. For example a red zebra midge in a size 14 and a black zebra midge in a size 18. On the right days you will find those midges hatching on surface. Look and watch very closely for small rises on the surface. Trout will not be working very hard to eat these flies and they barely break the surface of water. However they will eat a ton of midges. Look to the slow consistent moving water for these fish to be rising. Everything is open year around now except the Ranch and Ashton Dam to Vernon bridge. There are lots of spots you can snowshoe into and have a great day of fishing.

Fishing season  closed November 30th on the Ashton Dam to Vernon Bridge reach and will not re-open until Memorial Day, 2012.  The river below Ashton Dam has cleared significantly, and fishing has been good (streamers, small bead head nymphs, and midge life cycle patterns) downstream of the Vernon Bridge.   Access along the river is not impeded much by snow amounts.

Now for some information that will help you plan fishing on the lower river next season. First,  Ashton Reservoir will be refilled during the winter, but depending on run off conditions, the reservoir will be drawn down for the final time in late May, 2012.  Next, turbine issues at the Chester Dam mean that the rubber bladder on top of the dam will not be installed until fall, 2012 at the earliest.  This means water levels, and fish and insect activity in the Chester Dam backwaters and immediately above will be subject to run-off and weather conditions alone.   This delay also impacts full use of the dam’s new fish ladder.

The  river below Ashton Dam remains a bit discolored, but streamer patterns are working for those hardy souls getting out on the river.  Browns are migrating, and rainbows are stocking up for winter.   As we said on the South Fork report, pitching streamer patterns while moving around to find water where fish hole up helps keep one relatively warm. Yes, the river has good days for top water midging, too. On the upper river (check road conditions before going) snow from a foot or two to much more makes it tougher to get to Box Canyon or the Tubs to pitch streamers.

Expect turbidity spikes in the river below Ashton Dam as work on the outlet tunnel and coffer dam proceeds.  Midge emergences are big time on the lower river, and small bead head nymphs, pattern of your choice,  catch fish, but streamers are catching the biggest fish.   Box Canyon and The Tubs are the place for big fish on the upper river. Dress for the occasion if you venture to these.

Inspection work on Ashton Dam requires reducing flows as low as 300 cfs from time to time over the next week. This fluctuation will  impact turbidity in the river as well as fish activity.  PacifiCorp will begin filling Ashton Reservoir on November 28th.   Best news is that because Island Park Reservoir holds abundant water, flows out of Island Park Dam will be at least 500 cfs through the winter. This is great news for fish especially the youngest which need bank side water for shelter.  Best way to enjoy top water fishing on the river now is with midge life cycle patterns as BWOs will begin to diminish.  Nymph patterns will also work, but streamer fishing is the best way to encounter the largest fish these days.

Water quality has not improved below the Ashton Dam. We have been keeping in contact with a few individuals about this project and will update you as soon as we hear the water quality improves.

Warm River to Ashton stretch is fishing well with Blue Wing Olives, and midge Patterns. There are a few October Caddis out but nymphing seems to be the ticket for getting into large numbers of fish. Zebra Midge patterns and Mayfly bead head seem to be the most effective. Streamers have also been effective on the overcast days.
