Henry’s Fork

Jimmy's All Seasons Angler / Henry’s Fork (Page 23)

Henry’s Fork 5-12-12

The information Tim placed on the Henry’s Fork yesterday is good and informative, but lets now give you an alternative river location.  The Henry’s Lake Outlet section of the river is open to catch and release fishing with numerous cutts spawning in the upper reaches down into the Flat Ranch Preserve.  We fished here late last week, avoiding the spawning redds but trying adjacent cover. Any wooly bugger type or streamer was effective in catching not only cutts but brookies hanging around for drifting eggs. Even encountered a rainbow or two, but not the size we were hoping for.   Flow at the time was 140 cfs but has since dropped to 110 cfs ideal for wading.  As soon as the  general season opens this part of the river will be crowded and many fish will be creeled.  So enjoy it now.

Henry’s Fork 5/11

The release from the Ashton Dam was delayed and we believe that they will start to release water today. We will keep you all updated and although I don’t think the water quality will be fishable because they don’t have to do any excavation.

So far the only Stonefly action is on the warm river. some of them have been moved down to the stone bridge below the confluence of Warm River and Henry’s Fork. Caddis, March Browns, Blue Wing Olive and Stonefly nymphs have been effective on the lower river. Through Box Canyon you will find some BWO hatches and a few caddis hatches right now. Nymphing will be your best opportunity for hooking fish through the Box Canyon.

Ashton Reservoir draw-down begins tomorrow and will take two weeks to complete.  Expect discolored water during this event and for a while afterwards.  However, discolor should not be as bad as last September when unconsolidated sediments up to 100 years old moved out.   Impact on wet fly fishing is less likely than to dry fly fishing during draw-down.  A streamer pattern of the evening presented in areas out of direct sunlight remains the best way to encounter a large fish until stonefly nymphs begin moving.

Henry’s Fork 5/4

Flows on the Lower Henry’s Fork have seemed to level out from that warm spell we had last week that raised the water levels that discolored the water. Caddis, March Browns and Blue Wing olives have been hatching and fish have been receptive to a dry fly presentation. Nymphing has also been effective. I would fish 2 rubberlegs below an indicator right now focusing on stoneflies starting to move around. Just a few more weeks till we start seeing a major move of stonflies to the bank for the Salmon Fly hatch. I haven’t heard much about the streamer activity but I assume you should be able to move some fairly large fish right now with a big fly.

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.

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.
