What to tie on at Dover / Rochester Road Crossings
Picked from recent reports for this stretch.
Blood Dot Egg
Fall is spawning season for some trout and salmon. Egg patterns are crucial for opportunistic trout feeding below spawning fish.
Buy at AmazonBlue-Winged Olive (BWO) Comparadun
Blue-Winged Olives are a dominant hatch in the fall, especially on overcast days. This low-profile dry fly effectively imitates the adults for selective trout.
Buy at AmazonOctober Caddis (Dry)
Fall is prime time for the large October Caddis hatch. This dry fly imitates the adult caddis and can draw aggressive strikes.
Buy at AmazonMuddler Minnow
As water temperatures cool, trout become more predatory, actively feeding on baitfish and sculpins. The Muddler Minnow is a classic fall streamer.
Buy at AmazonTravis Hi-Vis BWO Para Emerger
As BWO hatches occur, trout often key in on vulnerable emergers struggling in the surface film. This high-visibility pattern helps detect subtle takes.
Black Woolly Bugger
A classic winter streamer that imitates leeches or sculpins; fish it with a very slow strip or dead-drift through deep pools.
Zebra Midge
Midges are the most consistent food source for Brook and Brown trout in New Hampshire during the late winter.
Buy at AmazonLittle Black Stonefly nymph
Winter stoneflies are among the few large aquatic insects active in February and are a high-protein target for trout.
Blue-Winged Olive Comparadun
Blue-Winged Olives are actively hatching in early spring, especially on overcast days, making this low-profile dry fly excellent for selective trout feeding on emergers and adults.
