Lamoille River Hatch Calendar at a Glance
The Lamoille is a longer river than most in Vermont and offers varied fishing. The upper reaches near Hardwick are smaller and hold mostly brook trout. The middle sections from Morrisville downstream through Johnson and Jeffersonville are the most productive trout water. Access is good along Route 15 and at several town parks.
Hatches on the Lamoille mirror other Vermont freestone rivers. Hendricksons in April and May are the signature spring hatch. Caddis dominate summer. The river tends to run clear and cold in its upper sections longer into summer than rivers at lower elevations.
The Lamoille Valley Rail Trail runs alongside portions of the river and provides walking access to water that would otherwise require long bushwhacks. This is particularly useful in the middle section between Hyde Park and Johnson where the trail opens up several miles of good trout water.

Check Conditions Near Lamoille RiverWhat to Fish
Ephemerella subvaria
Hendricksons on the Lamoille peak a week or two later than lower-elevation rivers due to the cooler northern Vermont climate. Early May afternoons in the pools between Hyde Park and Johnson are the best bet for rising fish during the hatch.
Recommended: Hendrickson #14
Trichoptera
Caddis are the most consistent hatch on the Lamoille across summer. June evenings along the rail trail access points in the middle section produce the most reliable rise activity.
Recommended: Elk Hair Caddis #14-16
Various
Terrestrials are the go-to in summer when hatches slow down. The open meadow sections near Johnson and Jeffersonville are productive with hopper and ant patterns cast tight to grassy banks.
Recommended: Hopper #10-12
Baetis spp.
Fall BWO hatches can be excellent on the Lamoille during overcast October days. The river holds fish well into fall and the hatches extend the dry fly season past what many anglers expect from a northern Vermont river.
Recommended: BWO Parachute #18
