April can be a brilliant month on the river – but it’s rarely straightforward. Hatches are more consistent, fish are looking up more often, yet they’ll still switch between surface, film and subsurface feeding through the day. This April River Hatch Pack is built for exactly that kind of fishing.
Each pack is tied on premium hooks, selected for reliability and neat proportions, and comes presented in a compact clip-lid compartment fly box – ideal for slipping straight into your vest or jacket pocket.
The emphasis is on dry flies and emergers, with a small supporting cast of proven nymphs and wets for those moments when fish stop showing but are very much still catchable.
What’s inside and why it’s there
-
Grannom Caddis Pupa Tungsten
A key early-season subsurface pattern. Perfect for fishing just before or during the grannom hatch when trout are intercepting pupae as they rise. The tungsten bead helps you get down quickly in faster spring flows.
-
Grannom Caddis CDC Emerger Barbless (Size 14)
A deadly pattern when fish are feeding just under the surface. The CDC keeps it sitting perfectly in the film, imitating emerging caddis that trout find hard to ignore.
-
CDC Hawthorn Barbless
Spring wouldn’t be complete without it. When hawthorns get blown onto the water, this fly can turn a quiet afternoon into something memorable. Especially effective on calmer glides and edges.
-
Deer Hair Emerger Barbless (Size 14)
One of those confidence patterns for tricky fish. Sits low, looks vulnerable, and works beautifully during olive activity when trout won’t commit to a high-floating dry.
-
Sawyer’s Pheasant Tail (Size 16)
A timeless nymph that still earns its place. Ideal when nothing is rising, or as a dropper under a dry when fish are feeding sub-surface.
-
All Round Olive Barbless
A versatile olive pattern that covers multiple bases. Use it as a straight dry, or as a searching fly when you know fish are present but not showing.
Who this pack is for
-
River anglers fishing April through early May
-
Those wanting a thought-through selection, not just random flies
-
Anglers who like to fish dries and emergers first, but still want solid backup options
A carefully balanced pack that reflects how rivers actually fish in April – adaptable, seasonal, and quietly effective.
