Month-by-month hatch timing, fly pattern recommendations, and current conditions for the Jemez River in 2026. The Jemez flows through a volcanic canyon in the Jemez Mountains northwest of Albuquerque with reliable BWO and caddis hatches and far less pressure than nearby San Juan.
Jemez River Hatch Calendar — Quick Reference
The Jemez River drains the Jemez Mountains northwest of Albuquerque, flowing through Valles Caldera and the town of Jemez Springs before dropping into a narrow canyon cut through pale volcanic tuff. The best fly fishing is in the canyon sections below Jemez Springs and through the Jemez River Canyon Scenic Byway. Public water is accessible along NM-4, though private land limits access in some sections.
Wild rainbow and brown trout occupy the canyon water. The Jemez is smaller and less publicized than the San Juan or Rio Chama, which keeps pressure manageable most of the year. Fish in the canyon are opportunistic and respond well to standard freestone presentations. The pale volcanic rock and cottonwood galleries along the canyon give the Jemez a distinct visual character.
BWO hatches run from early spring through late fall, with April and October being the peak months. Caddis activity is strong from May through August, with June evenings seeing the most consistent emergences. PMDs are present in June and July on the better canyon sections. The Autumn Caddis hatch in September and October brings fish up for larger dry flies to close out the season.
The Jemez Mountains are a popular weekend destination for Albuquerque residents, and campground areas near Jemez Springs can see significant foot traffic. The canyon sections away from the main recreation areas fish with much less pressure. Hot springs near Jemez Springs can warm sections of the river in summer, so targeting upstream canyon water or early morning fishing improves results in July and August.

Baetis sp.
BWOs run from early spring into late fall on the Jemez, with April and October being the most consistent hatch windows. Overcast days trigger the best emergences in the canyon. March hatches can start during winter warm spells. November BWO activity extends the season for dry fly fishing into the colder months. A Sparkle Dun or CDC Dun in size 18 to 22 covers most BWO situations on the Jemez.
Recommended: Sparkle Dun, CDC Dun #18-22
Hydropsyche sp.
Caddis is the most reliable evening hatch on the Jemez from May through August. June evenings produce the densest emergences, with fish rising along the edges of the canyon in the flatter pools. An Elk Hair Caddis in size 14 to 16 works throughout the season. Caddis activity overlaps with PMDs in May and June for the most productive surface fishing of the year on this stream.
Recommended: Elk Hair Caddis, X-Caddis #14-16
Neophylax sp.
The Autumn Caddis hatch on the Jemez arrives in September and peaks in October alongside fall foliage in the canyon. Large orange-bodied caddis emerge in the afternoon and fish respond to bigger dry flies after a summer of smaller patterns. An Orange Stimulator in size 12 to 14 is the go-to pattern. Fall is the least crowded time on the Jemez and often produces the most aggressive fish of the year.
Recommended: Orange Stimulator, October Caddis #12-14
Common Questions
The best fly fishing on the Jemez River is in the canyon sections below Jemez Springs, accessible via NM-4 through the Jemez River Canyon. Public water runs along much of the highway, but private land limits access in some spots. Sections away from campgrounds and recreation areas hold more fish and see less pressure. A New Mexico fishing license is required.
Yes, though it is often overlooked compared to the San Juan or Rio Chama. The Jemez holds wild rainbow and brown trout in the canyon sections and has consistent hatches from spring through fall. Its relative obscurity compared to better-known New Mexico trout streams means pressure is lower on most days. The volcanic canyon scenery is also a draw in its own right.
Late spring through early summer is the top window on the Jemez, when caddis and PMD hatches overlap in May and June. Fall is a close second, with October BWO and Autumn Caddis hatches producing aggressive fish in the cooler canyon water. Spring can be blown out by runoff from the Jemez Mountains, so checking water conditions before heading out in April is a good idea.
