Prairie River Hatch Calendar — Quick Reference
The Prairie River flows through Lincoln County in north-central Wisconsin. It sees far less pressure than the Brule or Kinnickinnic, which means undisturbed fish and good solitude. Wild brookies show up in the colder upper sections.
The Hex hatch in June draws the most attention from local anglers. Evening fishing with large dries after dark produces the best action of the season. Hopper fishing is productive on warm August afternoons along grassy banks.
Access is available through county and state forest lands along much of the river. The Prairie runs clear over rock and gravel, which allows sight fishing on calm mornings.

Check Conditions Near Prairie RiverWhat to Fish
Hexagenia limbata
The Hex is the main event on the Prairie River. Fish the flats and slower bends after dark on warm June nights with a large foam or hair-wing dry.
Recommended: Hex Parachute #6-8
Acrididae
Hopper fishing in August works well on the Prairie. Cast tight to grassy undercut banks in the afternoon for the most aggressive responses.
Recommended: Dave's Hopper #8-12
Trichoptera
Evening caddis hatches are reliable through the summer. A skating caddis can draw explosive strikes when fish are keying on adults skimming the surface.
Recommended: Elk Hair Caddis #14-16
Neophylax spp.
Fall caddis extend dry fly fishing into October. These larger orange-bodied sedges bring fish up on afternoon hatches well into the fall season.
Recommended: Orange Sedge #14
