The Tomorrow River in Waupaca County is a central Wisconsin gem with cold spring-fed flows and a healthy population of wild brown and brook trout. The hatch calendar is excellent from April through October.
Tomorrow River Hatch Calendar — Quick Reference
The Tomorrow is a productive freestone stream with a mix of riffles and deeper runs. Spring hatches start with Hendricksons in April and progress through March Browns and caddis into early summer. The Hex hatch in June is a consistent evening event.
Trico spinner falls in summer bring fish to the surface in slower pools. The fishing can get technical with small flies and long leaders. Isonychia hatches in September add a window of larger dry fly action heading into fall.
Access is good through the Tomorrow River State Fishery Area. The river runs clear and the trout are selective, so a careful approach pays off.

Hexagenia limbata
The Hex hatch brings the biggest dry fly action of the season on the Tomorrow. Large browns move to shallow water after dark on warm June evenings.
Recommended: Hex Parachute #6-8
Maccaffertium vicarium
March Browns hatch in May and often overlap with caddis. Afternoon hatches on overcast days trigger surface feeding across the whole riffle.
Recommended: March Brown Parachute #12-14
Trichoptera
Caddis are consistent through the summer on the Tomorrow. Evening hatches in June are the most reliable. A diving caddis or soft hackle works on fish that refuse the dry.
Recommended: Elk Hair Caddis #14-16
Tricorythodes spp.
Morning trico spinner falls in summer are a regular event on the slower pools. The tiny flies require patience and fine tippet, but the rising fish make it worth the effort.
Recommended: Trico Spinner #20-22
