What to tie on at Carbella Access
Picked from recent reports for this stretch.
Zebra Midge
A mandatory winter staple on the Yellowstone. In February, midge larvae are the most abundant food source; fish these in black or red sizes 18-22 behind a heavier nymph.

While stoneflies aren't hatching, the large nymphs are always present in the substrate. The tungsten version acts as a perfect 'anchor' to get your rig down to the bottom in heavy winter flows.
Buy at AmazonGriffith's Gnat
During the warmest part of the day, midges will cluster on the surface. This is your best and often only chance for dry fly action in February.
Woolly Bugger (Olive)
A versatile searching pattern that imitates leeches and baitfish, effective for enticing aggressive trout in varying water conditions.
Hare's Ear Nymph
An essential general searching nymph, mimicking various active mayfly nymphs that are always present in the river.

A classic imitation for the abundant caddis adults, including 'white miller caddis,' actively hatching now.
Buy at AmazonBlue-Winged Olive (BWO) Comparadun
Consistent BWO hatches are expected in early spring, especially on overcast days. This low-profile dry fly is excellent for selective trout feeding on emergers and adults.
Buy at AmazonBlack Woolly Bugger
A versatile streamer, effective year-round for predatory fish like trout, imitating leeches and baitfish. It's a high-percentage searching pattern for larger trout in higher flows.
