Henry’s Fork

Jimmy's All Seasons Angler / Henry’s Fork (Page 20)

Henry’s Fork 4-28-12

The river is running high with flows near double throughout.  Best chance to encounter large fish is through presenting streamer and large stonefly nymph patterns. Try Box Canyon and the top of the Chester backwaters with streamers.  Best times to try these are during low light conditions.  Try big stonefly nymphs in Box Canyon,  from Vernon Bridge down to top of Chester back waters, or Warm River to Ashton.   Don’t overlook the river in Bear Gulch and above Hatchery Ford for presenting both of these. These reaches have very little pressure and host a lot of big trout.

Fall River input has really increased, so forget fishing the river below Chester for a while.  Want an update on the construction activities at the Ashton Dam and their impact on fishing the river below?  Go to the Henry’s Fork Foundation web site.  Nymphing, late in the day streamer fishing on the river between Vernon Bridge and Chester backwaters has been pretty good recently, but a lot of folks are fishing this reach both wading and boating.  During wind free days fish are still responding to the BWO hatches.

Leave the river below Chester Dam alone because of run off coming from Fall River.  The river above to the Vernon Bridge (closed until general opening from there upstream to the Ashton Dam) offers some good afternoon fishing when BWO activity gets going.  Overcast, low wind (if you can find such!) days are best.  Caddisfly action is also giving fish reason to feed.  If you fish later in the day, be sure to have streamer patterns available.  During evenings large trout will be foraging, especially around parts of the river out of direct sunlight.  Presenting streamer patterns during this activity gives you the best chance for encountering a trophy this time of year.   Go to the Henry’s Fork Foundation web site for an update on activities at the Ashton Dam and for their outlook on construction impacts on fishing the river below for weeks to come.

Henry’s Fork 4/5

Water quality is still good on the Henry’s Fork. The Fall River is putting a little color into the river below Chester Dam but it is not enough to worry about. Midges have still been hatching in good numbers, not a lot of activity with Blue Wing Olives. BWO’s should be hatching in large numbers any day now. Nymphing and streamer fishing between the dry fly hatches have also been producing fish.

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.

Henry’s Fork 3/13

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.

Henry’s Fork 3-6-2012

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.

Henry’s For 2/2

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.

Henry’s Fork 12-6-2011

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.
