Fly Fishing Hook Sizes & Fly Patterns in Pittsburgh, PA
Discover the Right Hook Sizes and Proven Fly Patterns to Catch More Fish in Western Pennsylvania
When it comes to successful fly fishing in Pittsburgh and the surrounding rivers, creeks, and lakes, choosing the right hook size and fly pattern is key. Whether you’re casting into the Youghiogheny River, Slippery Rock Creek, or Loyalhanna Creek, knowing what works can make all the difference.
Understanding Fly Fishing Hook Sizes
Hook sizes for fly fishing range from tiny #32 (used for small midges) to large #2/0 hooks for streamers and big game.
For trout fishing in Western PA waters, here are the most commonly used hook sizes:
#12–#16: Great for dry flies like Adams, Elk Hair Caddis, and Blue-Winged Olives. Ideal for matching local hatches.
#16–#22: Best for midges and nymphs, especially on highly pressured waters like Neshannock Creek.
#8–#12: Excellent for terrestrials, stoneflies, and smaller streamers.
#6 and Larger: Use for big streamers when targeting bass or trout in deeper or faster-moving rivers.
Local Tip: In spring, fish tend to take larger patterns. By late summer, smaller hooks tend to produce more strikes.
Best Fly Patterns for Pittsburgh Fly Fishing
Pittsburgh’s fly fishing scene offers diverse opportunities year-round.
These “go-to” fly patterns have proven themselves on waters across Allegheny, Fayette, Westmoreland, and beyond:
1. Elk Hair Caddis (Size 14–16)
A reliable dry fly for early spring and late summer evenings. Excellent for trout during caddis hatches.
2. Pheasant Tail Nymph (Size 14–20)
One of the most productive nymphs for year-round fishing. Effective in both freestone and tailwater streams.
3. Woolly Bugger (Size 6–10)
A versatile streamer that works in just about every condition. Great for trout, smallmouth bass, and even steelhead.
4. San Juan Worm (Size 12–16)
Simple yet deadly. Best after rainfall or in stained waters when natural forage is washed into the streams.
5. Zebra Midge (Size 18–22)
Highly effective in winter and early spring when fish feed on small subsurface insects.
6. Green Weenie (Size 12–14)
A local favorite! Particularly effective in Pennsylvania waters. Simple, bright, and deadly for stocked and wild trout alike.
Pro Tip: Match the hatch by observing insect activity before tying on a fly. Seasonal patterns vary, so always bring a variety of sizes and types.
