Mother nature has been bringing us much needed moisture recently and it looks like it will be a wet week coming up. The valleys have been receiving rain, and snow is falling in the mountains, which will melt and help to fill our reservoir.
The benefit of fishing in this wet April weather is being able to cast over rising fish. The midge hatch is very strong on the upper 3 and the blue winged olive hatch remains the best down towards Bighorn Access. The dry fly fishing has been really good in the afternoons and into the evening. Many anglers get on the river early and off at dinner time and miss some the best dry fly fishing in the evenings.
In many areas you will find both hatches present at the same time. A CDC Sparkle Dun or other effective baetis pattern with a midge cluster trailed behind is a highly effective setup in many instances. The intensity of the hatch has been varying from day to day. Yesterday fish were up in every likely spot. Other days they have been in tight pods sporadically throughout the river.
Nymph fisherman have been having a lot of success throughout the day with sowbugs, midge pupa/larva and baetis nymphs. There has been a lot of midge pupa in stomach samples as of late. When taking samples it is good to be able to know the difference between midge pupa and larva.
Midges go through complete metamorphosis. Larva look like small worm/tube like organism. When midge larva transform into pupa, the head of the midge becomes more pronounced and you will notice the presence of wing buds. Once these wing buds develop the pupa will ascend to surface. Trout readily key in on both or either, the pupa or larva stages. The juju midge and root beer midge are two excellent examples of midge pupa that are highly effective patterns on the Bighorn. Both patterns have a synthetic wing over the thorax that imitates the wing buds.
Baetis nymphs in combination with a midge pupa or a sowbug has been really effective. The juju baetis, wonder nymph, jr’s flashback and black quill have all been great Bighorn BWO nymph imitations.
A few guys are still throwing streamers out there and moving some nice fish. Fishing streamers from the boat in between dry fly spots is a great way to fish this time of year.
